abstract = {Current research on systems and synthetic biology relies heavily on mathematical models of the systems under study. The usefulness of such models depends on the quantity and quality of biological data, and on the availability of appropriate modelling formalisms that can gather and accommodate such data so that they can be exploited properly. Given our incomplete knowledge of biological systems and the fact that they consist of many subsystems, biological data are usually uncertain and heterogeneous. These facts hinder the use of mathematical models and computational methods. In the scope of dynamic biological systems, e.g. metabolic networks, this difficulty can be overcome by the novel modelling formalism of flexible nets (FNs). We show that an FN can combine, in a natural way, a stoichiometric model and a kinetic model. Moreover, the resulting net admits nonlinear dynamics and can be analysed in both transient and steady states.},

abstract = {Availability of a common, shared benchmark to provide repeatable, quantifiable, and comparable results is an added value for any scientific community. International consortia provide benchmarks in a wide range of domains, being normally used by industry, vendors, and researchers for evaluating their software products. In this regard, a benchmark of untimed Petri net models was developed to be used in a yearly software competition driven by the Petri net community. However, to the best of our knowledge there is not a similar benchmark to evaluate solution techniques for Petri nets with timing extensions. In this paper, we propose an evaluation framework for the comparative analysis of generalized stochastic Petri nets (GSPNs) simulation techniques. Although we focus on simulation techniques, our framework provides a baseline for a comparative analysis of different GSPN solvers (e.g., simulators, numerical solvers, or other techniques). The evaluation framework encompasses a set of 50 GSPN models including test cases and case studies from the literature, and a set of evaluation guidelines for the comparative analysis. In order to show the applicability of the proposed framework, we carry out a comparative analysis of steady-state simulators implemented in three academic software tools, namely, GreatSPN, PeabraiN, and TimeNET. The results allow us to validate the trustfulness of these academic software tools, as well as to point out potential problems and algorithmic optimization opportunities.},

abstract = {Malicious applications pose as one of the most relevant issues in today's technology scenario, being considered the root of many Internet security threats. In part, this owes the ability of malware developers to promptly respond to the emergence of new security solutions by developing artifacts to detect and avoid them. In this work, we present three countermeasures to mitigate recent mechanisms used by malware to detect analysis environments. Among these techniques, this work focuses on those that enable a malware to detect dynamic binary instrumentation frameworks, thus increasing their attack surface. To ensure the effectiveness of the proposed countermeasures, proofs of concept were developed and tested in a controlled environment with a set of anti-instrumentation techniques. Finally, we evaluated the performance impact of using such countermeasures.},

Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment; when an analysis environment is detected, malware behaves as a benign application or even shows no activity. In this work, we present an empirical study and characterization of automatic public malware analysis services, considering 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis environments; the lower the unlikeability of these features, the easier for us (and thus for malware) to fingerprint the analysis service they belong to. Finally, we propose a method for these analysis services to counter or at least mitigate our proposal.},

abstract = {Memory forensics is a fundamental step in any security incident response process, especially in computer systems where malware may be present. The memory of the system is acquired and then analyzed, looking for facts about the security incident. To remain stealthy and undetected in computer systems, malware are abusing the code signing technology, which helps to establish trust in computer software. Intuitively, a memory forensic analyst can think of code signing as a preliminary step to prioritize the list of processes to analyze. However, a memory dump does not contain an exact copy of an executable file (the file as stored in disk) and thus code signing may be useless in this context. In this paper, we investigate the limitations that memory forensics imposes to the digital signature verification process of Windows PE signed files obtained from a memory dump. These limitations are data incompleteness, data changes caused by relocation, catalog-signed files, and executable file and process inconsistencies. We also discuss solutions to these limitations. Moreover, we have developed a Volatility plugin named sigcheck that recovers executable files from a memory dump and computes its digital signature (if feasible). We tested it on Windows 7 x86 and x64 memory dumps. Our experiments showed that the success rate is low, especially when the memory is acquired from a system that has been running for a long time.},

abstract = {Scientific workflows enable scientists to undertake analysis on large datasets and perform complex scientific simulations. These workflows are often mapped onto distributed and parallel computational infrastructures to speed up their executions. Prior to its execution, a workflow structure may suffer transformations to accommodate the computing infrastructures, normally involving task clustering and partitioning. However, these transformations may cause workflow imbalance because of the difference between execution task times (runtime imbalance) or because of unconsidered data dependencies that lead to data locality issues (data imbalance). In this paper, in order to mitigate these imbalances, we enhance the workflow lifecycle process in use by introducing a workflow imbalance phase that quantifies workflow imbalance after the transformations. Our technique is based on structural analysis of Petri nets, obtained by model transformation of a data-intensive workflow, and Linear Programming techniques. Our analysis can be used to assist workflow practitioners in finding more efficient ways of transforming and scheduling their workflows. Moreover, based on our analysis, we also propose a technique to mitigate workflow imbalance by data throttling. Our approach is based on autonomic computing principles that determine how data transmission must be throttled throughout workflow jobs. Our autonomic data-throttling approach mainly monitors the execution of the workflow and recompute data-throttling values when certain watchpoints are reached and time derivation is observed. We validate our approach by a formal proof and by simulations along with the Montage workflow. Our findings show that a dynamic data-throttling approach is feasible, does not introduce a significant overhead, and minimizes the usage of input buffers and network bandwidth.},

abstract = {Malicious lateral movement-based attacks have become a potential risk for many systems, bringing highly likely threats to critical infrastructures and national security. When launching this kind of attacks, adversaries first compromise a fraction of the targeted system and then move laterally to the rest of the system until the whole system is infected. Various approaches were proposed to study and/or defend against lateral movement-based attacks. However, few of them studied transient behaviors of dynamic attacking and dynamic targeted systems. This paper aims to analyze the transient security of a dynamic network system under lateral movement-based attacks from the time that attack-related abnormity in the system is detected until mechanisms are designed and deployed to defend against attacks. We explore state-space modeling techniques to construct a survivability model for quantitative analysis. A phased piecewise constant approximation approach is also proposed to derive the formulas for calculating model state transient probabilities, with which we derive formulas for calculating metrics of interest. The proposed approach allows both model state transition rates and the number of model states to be time-varying during the system recovery. Numerical analysis is carried out for investigating the impact of various dynamic system parameters on system security.},

In this paper, we present a UML profile to annotate sequence diagrams with combined fragments to model timed Web services with distributed resources under the Publish/Subscribe paradigm. This profile is exploited to automatically obtain a representation of the system based on Colored Petri nets using a novel model-to-model (M2M) transformation. This M2M transformation has been specified using QVT and has been integrated in a new add-on extending a state-of-the-art UML modelling tool. Generated Petri nets can be immediately used in well-known Petri net software, such as CPN Tools, to analyze the system behavior. Hence, our model-to-model transformation tool allows for simulating the system and finding design errors in early stages of system development, which enables us to fix them at these early phases and thus potentially saving development costs.},

abstract = {Malware detection is a challenge that has increased in complexity in the last few years. A widely adopted strategy is to detect malware by means of analyzing network traffic, capturing the communications with their command and control (C&C) servers. However, some malware families have shifted to a stealthier communication strategy, since anti-malware companies maintain blacklists of known malicious locations. Instead of using static IP addresses or domain names, they algorithmically generate domain names that may host their C&C servers. Hence, blacklist approaches become ineffective since the number of domain names to block is large and varies from time to time. In this paper, we introduce a machine learning approach using Random Forest that relies on purely lexical features of the domain names to detect algorithmically generated domains. In particular, we propose using masked N-grams, together with other statistics obtained from the domain name. Furthermore, we provide a dataset built for experimentation that contains regular and algorithmically generated domain names, coming from different malware families. We also classify these families according to their type of domain generation algorithm. Our findings show that masked N-grams provide detection accuracy that is comparable to that of other existing techniques, but with much better performance.},

abstract = {Computer forensics is performed during a security incident response process on disk devices or on the memory of the compromised system. The latter case, known as memory forensics, consists in dumping the memory to a file and analyzing it with the appropriate tools. Many security incidents are caused by malware that targets and persists as long as possible in a Windows system within an organization. The persistence is achieved using Auto-Start Extensibility Points (ASEPs), the subset of OS and application extensibility points that allow a program to auto-start without any explicit user invocation. In this paper, we propose a taxonomy of the Windows ASEPs, considering the features that are used or abused by malware to achieve persistence. This taxonomy splits into four categories: system persistence mechanisms, program loader abuse, application abuse, and system behavior abuse. We detail the characteristics of each extensibility point (namely, write permissions, execution privileges, detectability in memory forensics, freshness of system requirements, and execution and configuration scopes). Many of these ASEPs rely on the Windows Registry. We also introduce the tool Winesap, a Volatility plugin that analyzes the registry-based Windows ASEPs in a memory dump. Furthermore, we state the order of execution of some of these registry-based extensibility points and evaluate the effectiveness of our tool in memory dumps taken from a Windows OS where extensibility points were used. Winesap was successful in marking all the registry-based Windows ASEPs as suspicious registry keys.},

In particular, Petri nets (PNs) are a widely used formalism to model these systems. Although their functional properties have been extensively studied in the literature, their nonfunctional properties (such as throughput) have usually been ignored. In this brief, we focus on a PN subclass useful for modeling concurrent sequential processes with shared resources, termed S4PR nets. For these nets, we present an iterative strategy that makes intensive use of mathematical programming problems to approximate system throughput. Initially, our strategy selects the slowest part (a subsystem) of the net. Then, the next slowest parts are considered. In each step, the throughput is computed solving analytically the underlying continuous-time Markov chain when feasible (or by simulation, otherwise). Since only certain subsystems are considered, the state-explosion problem inherent to the increasing net size is mitigated. We evaluate our strategy in a set of randomly generated S4PR nets. Our findings show that the throughput improves the upper throughput bound computation by almost 20% and that small portions of the net are enough to approximate system throughput.},

Time-based, prediction-based rejuvenation of virtual machines (VM) and virtual machine monitors (VMM), VM failover, and live VM migration are common high-availability (HA) techniques in a virtualized system. This paper investigates the effect of combination of these availability techniques on VM availability in a virtualized system where various software and hardware failures may occur. For each combination, we construct analytic models rejuvenation mechanisms improve VM availability; (2) prediction-based rejuvenation enhances VM availability much more than time-based VM rejuvenation when prediction successful probability is above 70%, regardless failover and/or live VM migration are also deployed; (3) failover mechanism outperforms live VM migration, although they can work together for higher availability of VM. In addition, they can combine with software rejuvenation mechanisms for even higher availability; (4) and time interval setting is critical to a time-based rejuvenation mechanism. These analytic results provide guidelines for deploying and parameter setting of HA techniques in a virtualized system.},

This paper aims to apply analytical modeling and sensitivity analysis techniques to investigate the impact of these factors on the availability of a large-scale IaaS CDC, which (1) consists of active and two kinds of standby physical machines (PMs), (2) allows PM moving among active and two kinds of standby PM pools, and (3) allows active and two kinds of standby PMs to have different mean repair times. Two repair policies are considered: (P1) all pools share a repair station and (P2) each pool uses its own repair station. We develop monolithic availability models for each repair policy by using Stochastic Reward Nets and also develop the corresponding scalable two-level models in order to overcome the monolithic model¿s limitations, caused by the large-scale feature of a CDC and the complicated interactions among CDC components. We also explore how to apply differential sensitivity analysis technique to conduct parametric sensitivity analysis in the case of interacting submodels. Numerical results of monolithic models and simulation results are used to verify the approximate accuracy of interacting sub-models, which are further applied to examine the sensitivity of the large-scale CDC availability with respect to repair policy and system parameters.},

abstract = {Finding identical digital objects (or artifacts) during a forensic analysis is commonly achieved by means of cryptographic hashing functions, such as MD5, SHA1, or SHA-256, to name a few. However, these functions suffer from the {\em avalanche} effect property, which guarantees that if an input is changed slightly the output changes significantly. Hence, these functions are unsuitable for typical digital forensics scenarios where a forensics memory image from a likely compromised machine shall be analyzed. This memory image file contains a snapshot of processes (instances of executable files) which were up on execution when the dumping process was done. However, processes are relocated at memory and contain dynamic data that depend on the current execution and environmental conditions. Therefore, the comparison of cryptographic hash values of different processes from the same executable file will be negative. Bytewise approximation matching algorithms may help in these scenarios, since they provide a similarity measurement in the range $[0,1]$ between similar inputs instead of a yes/no answer (in the range $\{0,1\}$). In this paper, we introduce ProcessFuzzyHash, a Volatility plugin that enables us to compute approximation hash values of processes contained in a Windows memory dump.},

By severe, we mean that the vulnerability-based malware could causesignificant damage to the infected system in terms ofsecurity and dependability while infecting more and morenew vulnerable computer systems. We propose a Markov chain-based survivability model for capturing thevulnerable critical system behaviors during the vulnerability elimination process. A high-level formalism based on Stochastic Reward Nets is applied to automaticallygenerate and solve the survivability model. Survivabilitymetrics are defined to quantify system attributes. The proposed model and metrics not only enable us toquantitatively assess the system survivability in terms ofsecurity risk and dependability, but also provide insights onthe system investment decision. Numerical experiments areconstructed to study the impact of key parameters on systemsecurity, dependability and profit.},

Formal methods have often been advocated as necessary to ensure the reliability of software systems, albeit with a considerable effort. In any case, such an effort is cost-effective when verifying safety-critical systems. Often, safety requirements are expressed using safety contracts, in terms of assumptions and guarantees. To facilitate the adoption of formal methods in the safety-critical software industry, we propose a methodology based on well-known modelling languages such as UML and OCL. UML is used to model the software system while OCL is used to express the system safety contracts within UML. In the proposed methodology a UML model enriched with OCL constraints is transformed to a Petri net model that enables to formally verify such safety contracts. The methodology is evaluated on an industrial case study. The proposed approach allows an early safety verification to be performed, which increases the confidence of software engineers while designing the system.},

These data, when remain at memory, are scraped and exfiltrated by specially crafted malicious software named POS RAM scraping malware. In recent years, large data breaches occurred in well-known US retail companies were caused by this kind of malware. In this paper, we study the features of these malware based on their behavior on different stages: infection and persistence, process and data of interest search, and exfiltration. Then, we classify samples of 22 known POS RAM scraping malware families from 2009 to 2015 according to these features. Our findings show these malware are still immature and use well-defined behavioral patterns for data acquirement and exfiltration, which may make their malicious activity easily detectable by process and network monitoring tools.},

abstract = {The theft of personal information to fake the identity of a person is a common threat normally performed by individual criminals, terrorists, or crime rings to commit fraud or other felonies. Recently, the Spanish identity card, which provides enough information to hire on-line products such as mortgages or loans, was updated to incorporate a Near Field Communication (NFC) chip as electronic passports do. This contactless interface brings a new attack vector for criminals, who might take advantage of the RFID communication to virtually steal personal information. In this paper, we consider as case study the recently deployed contactless Spanish identity card assessing its security against identity theft. In particular, we evaluated the security of one of the contactless access protocol as implemented in the contactless Spanish identity card, and found that no defenses against on-line brute-force attacks were incorporated. We then suggest two countermeasures to protect against these attacks. Furthermore, we also analyzed the pseudo-random number generator within the card, which passed all the performed tests with good results.},

Several services are found on the Internet that provide to users automatic system to analyze malware samples, as VirusTotal, Jotti, or ClamAV, to name a few. Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment. When analysis environment is detected, malware behave as a benign application or even show no activity. In this work, we present an empirical study and characterization of automatic public malware analysis services. In particular, we consider 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis environments. Finally, we propose a method to mitigate fingerprinting.},

Abstract = {Malicious software specially crafted to proliferate in mobile platforms are becoming a serious threat, as reported by numerous software security vendors during last years. Android and iOS are nowadays the leaders of mobile OS market share. While malware targeting Android are largely studied, few attention is paid to iOS malware. In this paper, we fill this gap by studying and characterizing malware targeting iOS devices. To this regard, we study the features of iOS malware and classify samples of 36 iOS malware families discovered between 2009 and 2015. We also show the methodology for iOS malware analysis and provide a detailed analysis of a malware sample. Our findings evidence that most of them are distributed out of official markets, target jailbroken iOS devices, and very few exploit any vulnerability.},

Abstract = {Critical infrastructures as water treatment, power distribution, or telecommunications provide essential services to our day-to-day basis. Any service discontinuity may have a high impact into our society and even our safety. Thus, security of these systems against intentional threats must be guaranteed. However, many of these systems are based on protocols initially designed to operate on closed, unroutable networks, making them an easy target for cybercriminals. In this regard, Modbus is a widely adopted protocol in control systems. Modbus protocol, however, lacks for security properties and is vulnerable to plenty of attacks (as spoofing, flooding, or replay to name a few). In this paper, we propose a formal modeling of Modbus protocol using an extension of hierarchical state-machines that is automatically transformed to a Promela model. This model allows us to find counterexamples of security properties by model-checking. In particular, in this paper we prove the existence of man-in-the-middle attack in Modbus protocol. Our approach also allows to formally evaluate security properties in future extensions of Modbus protocols.},

Abstract = {The deployment of IP multicast protocols in each
router in the path is needed to access the benefits of the
multicast. IP multicast exists today mainly in LAN networks
and in small areas of highly controlled interconnected
networks. In fact, some companies started to offer tailored
solutions to try to overcome these limitations. On the other
hand, over the last decade, the multimedia applications have
expanded rapidly, and in particular in video applications.
There are Internet sites that offer movies on-line; and it is
common with applications, such as Skype (\copyright Microsoft). The
growth of video traffic should be taken into account when
designing a network. Understanding the behavior of the video
traffic and the requirements for the network helps network
administrators to improve the traffic planning. In this work, a
quantitative analysis is performed by experimentation, in
order to evaluate the behavior and impact of video traffic on
WAN networks. We propose a WAN test bed composed by a
video traffic server and several client stations that allows
injecting unicast and multicast video traffic, compressed with
several codecs. From capturing video traffic, we identified
several interesting unicast and multicast performance metrics,
such as: throughput, number of frames, delays, jitter, and
interframe spaces and frame sizes distributions. Several
factors have been taken into account: the video resolution
configuration, the type of video, and restrictions on the
bandwidth, as in a corporate real WAN link of some few
Mbps. This study facilitates the comparison of the results with
those obtained from analytical and modelling studies for
different contexts.},

Abstract = {Model checking has been recently introduced as an integrated framework for extracting information of the phylogenetic trees using temporal logics as a querying language, an extension of modal logics that imposes restrictions of a boolean formula along a path of events. The phylogenetic tree is considered a transition system modeling the evolution as a sequence of genomic mutations (we understand mutation as different ways that DNA can be changed), while this kind of logics are suitable for traversing it in a strict and exhaustive way. Given a biological property that we desire to inspect over the phylogeny, the verifier returns true if the specification is satisfied or a counterexample that falsifies it. However, this approach has been only considered over qualitative aspects of the phylogeny.},

Abstract = {A Fault Tree (FT) defines an undesired top event, characterizing it using logic combinations of lower-level undesired events. In this paper, we focus on coherent FTs, i.e., the logic is restricted to AND/OR formulae. Fault Tree analysis is used to identify and assess the Minimal Cut Sets (MCS) of an FT, which define the minimal set of events leading to the undesired state. The dual of MCS is Minimal Path Set (MPS). MCS and MPS are commonly used for qualitative evaluation of FTs in safety and reliability engineering. This paper explores computation of the MCS/MPS of an FT by means of structural analysis (namely, computation of minimal p-semiflows) of a Petri net that represents the FT. To this end, we propose a formal definition of a coherent FT and a transformation from this model to a Petri net subclass (namely, structurally persistent nets). We also prove the relationship between minimal p-semiflows and MCS/MPS in an FT. In addition, we propose an algorithm that uses linear programming techniques to compute the MCS/MPS in an FT. Finally, we put our findings into practice by qualitatively evaluating the FT of a pressure tank system.},

Abstract = {Computer systems are potentially targeted by cybercriminals by means of specially crafted malicious software called Advanced Persistent Threats (APTs). As a consequence, any security attribute of the computer system may be compromised: disruption of service (availability), unauthorized data modification (integrity), or exfiltration of sensitive data (confidentiality). An APT starts with the exploitation of software vulnerability within the system. Thus, vulnerability mitigation strategies must be designed and deployed in a timely manner to reduce the window of exposure of vulnerable systems. In this paper, we evaluate the survivability of a computer system under an APT attack using a Markov model. Generation and solution of the Markov model are facilitated by means of a high-level formalism based on stochastic Petri nets. Survivability metrics are defined to quantify security attributes of the system from the public announcement of a software vulnerability and during the system recovery. The proposed model and metrics not only enable us to quantitatively assess the system survivability in terms of security attributes but also provide insights on the cost/revenue trade-offs of investment efforts in system recovery such as vulnerability mitigation strategies. Sensitivity analysis through numerical experiments is carried out to study the impact of key parameters on system secure survivability.},

Abstract = {Security mechanisms are at the base of modern computer systems, demanded to be more and more reactive to changing environments and malicious intentions. Security policies unable to change in time are destined to be exploited and thus, system security compromised. However, the ability to properly change security policies is only possible once the most effective mechanism to adopt under specific conditions is known. This paper proposes a model-based approach to accomplish this goal: a vulnerability model of the system is built by means of a model-based, layered security approach, and used to quantitatively evaluate the best protection mechanism at a given time and hence, to adapt the system to changing environments. The evaluation relies on the use of a powerful, flexible formalism such as Dynamic Bayesian Networks.},

Abstract = {Malware analysis tools have evolved in the last years providing tightly controlled sandbox and virtualised environments where malware is analysed minimising potential harmful consequences. Unfortunately, malware has advanced in parallel, being currently able to recognise when is running in sandbox or virtual environments and then, behaving as a non-harmful application or even not executing at all. This kind of malware is usually called analysis-aware malware. In this paper, we propose a tool to detect the evasion techniques used by analysis-aware malware within sandbox or virtualised environments. Our tool uses Dynamic Binary Instrumentation to maintain the binary functionality while executing arbitrary code. We evaluate the tool under a set of well-known analysis-aware malware showing its current effectiveness. Finally, we discuss limitations of our proposal and future directions.},

Abstract = {During the last years, criminals have become aware of how digital evidences that lead them to courts and jail are collected and analyzed. Hence, they have started to develop anti-forensic techniques to evade, hamper, or nullify their evidences. Nowadays, these techniques are broadly used by criminals, causing the forensic analysis to be in a state of decay. To defeat against these techniques, forensic analyst need to first identify
them, and then to mitigate somehow their effects. In this paper, we review the anti-forensic techniques and propose a new taxonomy that relates them to the initial phase of a forensic process mainly affected by each technique. Furthermore, we introduce mitigation techniques for these anti-forensic techniques, considering the chance to overcome the anti-forensic techniques and the difficulty to apply them.},

Abstract = {The verification of safety becomes crucial in critical systems where human lives depend on the correct functioning of such systems. Formal methods have often been advocated as necessary to ensure the reliability of software systems, albeit with a considerable effort. In any case, such an effort is cost-effective when verifying safety-critical systems. Safety requirements are usually expressed using safety contracts, in terms of assumptions and guarantees. To facilitate the adoption of formal methods in the safety-critical software industry, we propose the use of well-known modelling languages, such as UML, to model a software system, and the use of OCL to express the system safety contracts within UML. A UML model enriched with OCL constraints is then transformed to a Petri net model that enables to formally verify such safety contracts. We apply our approach to an industrial case study that models a train doors controller in charge of the opening and closing of train doors. Our approach allows to perform an early safety verification, which increases the confidence of software engineers while designing the system.},

Abstract = {The multifaceted nature of cyber-physical systems needs holistic study methods to detect essential aspects and interrelations among physical and cyber components. Like the systems themselves, security threats feature both cyber and physical elements. Although to apply divide et impera approaches helps handling system complexity, to consider just one aspect at a time does not provide adequate risk awareness and hence does not allow to design the most appropriate countermeasures. To support this claim, in this paper we provide a joint application of two model-driven techniques for physical and cyber-security evaluation. We apply two UML profiles, namely SecAM (for cyber-security) and CIP\_VAM (for physical security), in combination. In such a way, we demonstrate the synergy between both profiles and the need for their tighter integration in the context of a reference case study from the railway domain.},

network administrators to improve the traffic. In this work, a
quantitative analysis is performed by experimentation, in order
to evaluate the behavior and impact of video traffic on WAN
networks. We propose a WAN test bed composed by a video
scenario that allows to inject multicast video traffic, compressed
with several codecs. From capturing video traffic, we identified
several interesting performance metrics, such as multicast
throughput, interframe space and frame size distributions, and
the number of frames. We include detailed contributions on the
impact produced by several factors, such as the configuration of
the resolution of the video, the video class, the codec used for the
compression, and the use of multicast traffic when there are
restrictions on the bandwidth, as in a corporate real WAN link of
some few Mbps. This study facilitates the comparison of the
results with those obtained from analytical studies and modelling
for different contexts.},

Abstract = {Functional and non-functional properties analysis (i.e., dependability, security, or performance) ensures that requirements are fulfilled during the design phase of software systems. However, the Unified Modelling Language (UML), standard de facto in industry for software systems modelling, is unsuitable for any kind of analysis but can be tailored for specific analysis purposes through profiling. For instance, the MARTE profile enables to annotate performance data within UML models that can be later transformed to formal models (e.g., Petri nets or Timed Automatas) for performance evaluation. A performance (or throughput) estimation in such models normally relies on a whole exploration of the state space, which becomes unfeasible for large systems. To overcome this issue upper throughput bounds are computed, which provide an approximation to the real system throughput with a good
complexity-accuracy trade-off. This paper introduces a tool, named PeabraiN, that estimates the performance of software systems via their UML models. To do so, UML models are transformed to Petri nets where performance is estimated based on upper throughput bounds computation. PeabraiN also allows to compute other features on Petri nets, such as the computation of upper and lower marking place bounds, and to simulate using an approximate (continuous) method. We show the applicability of PeabraiN by evaluating the performance of a building closed circuit TV system.},

Abstract = {Critical infrastructures, usually designed to handle disruptions caused by human errors or random acts of nature, define assets whose normal operation must be guaranteed to maintain its essential services for human daily living. Malicious intended attacks to these targets need to be considered during system design. To face with these situations, defense plans must be developed in advance. In this paper, we present a UML profile, named SecAM, that enables the modelling and security specification for critical infrastructures during the early phases (requirements, design) of systems development life-cycle. SecAM endows security assessment, through survivability analysis, of different security solutions before system deployment. As a case study, we evaluate the survivability of the Saudi Arabia crude-oil pipeline network under two different attack scenarios. The stochastic analysis, carried out with Generalized Stochastic Petri nets, quantitatively estimates the minimisation of attack damages into the crude-oil network.},

Abstract = {Code analysis, static or dynamic, is a primary mean for improving correctness and performance of software applications. Dynamic binary analysis (DBA) refers the methods to analyse runtime behaviour of binary code. Nowadays, DBA tools are implemented using dynamic binary instrumentation (DBI) frameworks, which can add arbitrary code into the execution flow of the binary. Unfortunately, a DBA tool increases the execution time of the analysed binary dramatically, as extra code is being executed. Experiments got figures with increments of 26x. Therefore, it is crucial for DBA tool construction to know exact figures about such penalties and their roots. Hence, we conduct a performance evaluation of leading DBI frameworks, namely Pin, Valgrind, and DynamoRIO, for which we have built a benchmark selecting a bunch of representative tools. The evaluation that we procure here provides guidance to choose the best DBI framework suited for different needs. Moreover, the benchmark by itself is a tool ready to be eventually used for performance evaluation of future DBI frameworks.},

Abstract = {Safety becomes a primordial assessment in safety-related systems where human lives can be somehow put in risk, needing to comply with safety requirements defined by industry standards such as IEC 61508, ISO 26262 or DO-178C. Safety contracts are useful to specify these requirements (as assumptions and guarantees), thus assuring an expected level of confidence. To verify the safety requirements is measured to represent more than a half of the overall system development costs. In this paper, we propose a model-based verification that addresses safety verification from the early beginning of system development, thus saving costs. Namely, we use UML for system design and Object Constraint Language (OCL) for specifying safety contracts, while its verification is carried out using Petri nets. As case study, we assess the safety of an embedded system that models a fire prevention system in a hospital building.},

Abstract = {Safety-critical systems (such as those in automotive, avionics, railway domains), where a failure can result in accidents with fatal consequences, need to certify their products as per domain-specific safety standards. Safety certification is not only time consuming but also consumes the project budget. Adopting a reuse oriented development and certification paradigm can be highly beneficial in such systems. Though there had been several research efforts on cost models in the context of software reuse as well as software product lines, none of them have addressed the certification related costs. In this paper, we present a cost model for software product lines, which incorporates certification costs as well. We first propose a mathematical model to represent a Software Product Line and then present an approach to compute, using optimisation theory, the set of artifacts that compose a new product assuring an expected level of confidence (that is, a certain Safety Integrity Level) at an optimised cost level. The proposed approach can help developers and software project managers in making efficient design decisions in relation to the choice of the components for a new product variant development as part of a product line.},

Abstract = {Design and operation of manufacturing systems and their supply chains is a domain of significant
research worldwide. The complexity of this domain stems from the large dimension of such systems
that are highly parallel and distributed, from significant sources of uncertainties and from the degrees
of flexibility. Formal methods are mathematical techniques, often supported by tools, for developing
man-made systems. Formal methods and mathematical rigor enable manufacturing engineers to
handle fundamental design principles, such as abstraction or modular and hierarchical development,
and to deal with typical engineering problems and quality goals, like reliability, flexibility, and
maintainability. Formal methods can provide both a deep understanding of the system, thus helping
to cover holes in the specification, and an improved system reliability, through verification and
validation of the desired properties. Automata, statecharts, queueing networks, Petri nets, min-max
algebras, process algebras, and temporal logic-based models are becoming more and more used for
an integrated view of design specification, validation, performance evaluation, planning, scheduling
and control of manufacturing systems and their supply chains.
This book presents some of the most significant works representing the state of the art in the
area of formal methodologies for manufacturing systems, combining fundamentals and advanced
issues. It is divided into four main parts, each devoted to a specific issue: modelling and simulation,
supervisory control (including deadlock prevention), performance evaluation (including scheduling
and optimization), and fault diagnosis and reconfiguration. Several formalisms are considered,
including finite state automata, Petri nets (discrete, timed, continuous, and hybrid), process algebra
and max-plus algebra, exemplifying the advantages of each of them in the solution of a specific
problem.Within each part, more detailed problems are considered, and themost significant solutions
are discussed and illustratedwith a series of interesting and significant examples in themanufacturing
area. Individual chapters are written by leading experts in the field. Each topic is illustrated in detail,
its significance in manufacturing systems is underlined, and the most important contributions
in that specific area are surveyed.
The book is intended for researchers, postgraduate students and engineers interested in problems
occurring in manufacturing systems. In particular, it provides a comprehensive overview of the most
important formal model-based solutions to a series of major problems in manufacturing systems and
their supply chains, which are based on formal and rigorous modelling of the underlying system.
Each chapter in the book aims at providing a balance mixture of (1) fundamental theory, giving
the reader a clear introduction to the most important formalisms used for the modelling, analysis
and control of manufacturing systems; (2) tutorial value, providing the state of the art on a series
of problems that occur in manufacturing systems, such as deadlock prevention, supervisory control,
performance evaluation and fault diagnosis; and (3) applicability, presenting a series of case studies
and applications taken from the industrial world, that make it particularly appealing to practitioners.
A brief description of the book is as follows. Part I (Chapters 1 through 5) concerns modelling
and simulation of manufacturing systems. Chapter 1 focuses on Petri nets (untimed and timed) and
shows how these can be effectively used to represent manufacturing systems in a bottom-up and
modular fashion. Chapter 2 deals with a particular class of manufacturing systems for which a
linear representation in an algebraic structure called dioids can be given. Chapters 3 and 4 deal
with hybrid models of manufacturing systems. In particular, Chapter 3 focuses on hybrid Petri nets
(HPNs), a formalism that combines fluid and discrete event dynamics. Particular attention is devoted
to first-order hybrid Petri nets (FOHPNs) whose continuous dynamics are piecewise constant. It is
shown how FOHPNs can be effectively used to model both manufacturing systems and inventory
control systems. Chapter 4 focuses on stochastic flow models (SFMs) that preserve the essential
features needed to design effective controllers and potentially optimize performance without any need
to estimate the corresponding optimal performance value with accuracy. An overview of recently
developed general frameworks for infinitesimal perturbation analysis (IPA) is also presented, through
which unbiased performance sensitivity estimates of typical manufacturing performance measures
can be obtained in such SFMs with respect to various controllable parameters of interest. Finally,
Chapter 5 deals with a problem occurring in many real manufacturing systems, namely, freight
transportation. It reviews the established transportation system modelling, including theory and
applications of transportation supply models, trip demand models and dynamic traffic assignment
methods, both for passenger and freight transportation, and also points out the characteristics of
freight transportation that influence the logistic chain performance.
Part II (Chapters 6 through 12) is devoted to the supervisory control of manufacturing systems.
In particular, Chapters 6 through 8 introduce deadlock avoidance/prevention policies; Chapters 9
through 12 deal with supervisory control problems. Chapter 6 addresses the problem of deadlock
avoidance in flexibly automated manufacturing systems through the modelling abstraction of the
(sequential) resource allocation system (RAS). The pursued analysis uses concepts and results from
the formalmodelling framework of finite state automata (FSA). Chapter 7 investigates the problem of
deadlock prevention in the Petri net framework. After an overview of the classical approaches based
on the addition of monitors that prevent siphons to become empty, a novel methodology is presented.
Chapter 8 also deals with Petri nets. Here the digraph theory is used to effectively derive control
laws that avoid deadlocks in single unit RAS, that is, systems where each part requires a single unit
of a single resource for each operation. In Chapter 9, Petri nets are used to solve supervisory control
problems of manufacturing systems. Different problem statements, depending on the considered
specifications, and different solutions are considered, in particular based on the theory of monitor
places and on the theory of regions. Extended finite automata (EFA), that is, automata augmented
with bounded discrete variables, and updates of these variables on the transitions, are introduced
in Chapter 10 and effectively used to automatically synthesize a supervisor. Decentralized control
and modular control problems are discussed in Chapter 11. Finally, Chapter 12 discusses how
manufacturing systems can often be modeled as max-plus-linear (MPL) systems and controlled via
model predictive control (MPC).
Part III (Chapters 13 through 20) addresses the issue of performance evaluation of manufacturing
systems and supply chains. Chapter 13 discusses approaches based on coloured Petri nets and
state space analysis. Performance evaluation and control of manufacturing systems using fluid (i.e.,
continuous) Petri nets are discussed in Chapter 14. Chapter 15, discusses how timed process algebra
called bounded true concurrency (BTC) can be effectively used for performance evaluation of flexible
manufacturing systems. The problem of designing the lean, that is, the smallest buffers necessary and
sufficient to achieve the desired line performance, is addressed in Chapter 16. Chapter 17 deals with
the issue of inventory allocation and cycle time improvement in manufacturing systems and supply
chains. Chapter 18 covers timed weighted event graphs, a subclass of Petri nets whose transitions
are associated with workshops or specific treatments and whose places represent storages between
the transitions. It deals with the minimization of the overall capacities of places, under throughput constraints.
Chapter 19 focuses on the application of Petri nets to the scheduling of semiconductor manufacturing systems.
To this aim, a hierarchical coloured timed Petri net (HCTPN) is proposed and genetic algorithms
are extended and then embedded into the constructed HCTPN to find optimal/suboptimal schedules.
Finally, Chapter 20 focuses on organization problems of health-care systems, presenting a Petri
net-based software for health-care service modelling and simulation called MedPRO. Resource
planning and scheduling are also in the scope of the tool.
Finally, Part IV (Chapters 21 through 23) illustrates fault diagnosis approaches for discrete event
systems that can be successfully applied to manufacturing systems. In particular, in Chapters 21 and
22 finite state automata and interpreted Petri nets, respectively, are used as reference formalisms.
In both chapters, diagnosability analysis is also performed. Chapter 21 also discusses the problem
of sensor selection for diagnosability and the problem of cooperative diagnosis for systems with
decentralized information. Chapter 23 addresses a problem strictly related to fault diagnosis occurring
in automated manufacturing systems, namely, that of online control reconfiguration.},

Abstract = {The Time Petri Net with firing frequency intervals (TPNF) is a modeling formalism used
to specify system behavior under timing and frequency constraints.
Efficient techniques exist to evaluate the performance of TPNF models based on the
computation of bounds of performance metrics (e.g., transition throughput, place marking).
In this paper, we propose a min-max problem to compute the cycle time of a transition
under optimistic assumptions. That is, we are interested in computing the lower bound.
We will demonstrate that such a problem is related to a maximization linear programming
problem (LP-max) previously stated in the literature,
to compute the throughput upper bound of the transition.
The main advantage of the min-max problem compared to the LP-max is that, besides the
optimal value, the optimal solutions provide useful feedback to the analyst
on the system behavior (e.g., performance bottlenecks).
We have implemented two solution algorithms, using CPLEX APIs,
to solve the min-max problem, and have
compared their performance using a benchmark of TPNF models,

Abstract = {The Time Petri Net with firing frequency intervals (TPNF) is a modeling formalism used
to specify system behavior under timing and frequency constraints.
Efficient techniques exist to evaluate the performance of TPNF models based on the
computation of bounds of performance metrics (e.g., transition throughput, place marking).
In this paper, we propose a min-max problem to compute the cycle time of a transition
under optimistic assumptions. That is, we are interested in computing the lower bound.
We will demonstrate that such a problem is related to a maximization linear programming
problem (LP-max) previously stated in the literature,
to compute the throughput upper bound of the transition.
The main advantage of the min-max problem compared to the LP-max is that, besides the
optimal value, the optimal solutions provide useful feedback to the analyst
on the system behavior (e.g., performance bottlenecks).
We have implemented two solution algorithms, using CPLEX APIs,
to solve the min-max problem, and have
compared their performance using a benchmark of TPNF models,
several of these being case studies.
Finally, we have applied the min-max technique for the vulnerability
analysis of a critical infrastructure, i.e., the Saudi Arabian crude-oil distribution network.},

performance of the network, and simultaneously comply with the

make the adjustment of these parameters dynamically, which we
call Algorithm for the Differentiation of Traffic Multiple

with noise, reaching a initialization effective, rapid convergence,
and the differentiation of effective multiple wireless traffic (voice,
video and best effort with Pareto distribution). It adopted a

Abstract = {A critical system must fulfil its mission despite the presence of security issues. These systems are usually deployed in heterogeneous environments, where they are subject to suffer security issues, such as intrusion attempts, confidential data theft or other type of attacks. Systems usually need to be redesigned after a security disaster, which can lead to severe consequences, such as the huge cost of reimplementing or redeploying all the system, as well as economic losses. Security has to be conceived as an integral part of the development process and as a singular need of what the system should perform (i.e., a non-functional requirement). Thus, when designing critical systems it is fundamental to study the attacks that may occur and plan how to react to them, in order to keep fulfilling the system functional and non-functional requirements. Despite considering security issues, it is also necessary to consider the costs incurred to guarantee a certain security level in critical systems. In fact, security costs can be very relevant and may span along different dimensions, such as budgeting, performance and reliability. Many of these critical systems that incorporate Fault-Tolerant (FT) techniques to deal with security issues are complex systems using resources that are compromised (i.e., they fail) by the activation of faults. These systems can be naturally modelled as Discrete Event Systems (DES) where resources are shared, also called Resource Allocation Systems (RAS). In this dissertation, we focus on FT systems using shared resources modelled as Petri nets (PNs) as formal model language. These systems are usually so large that make the exact computation of their performance a highly complex computational task, due to the well-known state explosion problem. As a result, a task that requires an exhaustive state space exploration becomes unachievable in reasonable time for large systems. The main contribution of this dissertation is threefold. Firstly, we provide different models, expressed by means of the Unified Modelling Language (UML) and Petri nets (PNs), to bring security and FT issues into foreground while designing, then allowing the analysis of security-performance trade-off. Secondly, we provide several algorithms to compute the performance (also performability -- i.e., performance under failure conditions) by means of upper throughput bounds, then avoiding the state space explosion problem. Lastly, we provide algorithms to compensate the throughput degradation produced by an unexpected situation in a FT system.},

In this paper we propose a transformation from UML State-Machine diagrams to Erlang code. Erlang is a functional language, with strict evaluation, single assignment, and dynamic typing, and with good support for concurrency and distribution. The contribution of this transformation is twofold: it can reduce development time, and moreover it permits us to validate UML diagrams at an early development stage through the use of Erlang-based model checking techniques.},

Abstract = {Many artificial systems can be modeled as discrete dynamic systems in which resources are shared among different tasks. The performance of such systems, which is usually a system requirement, heavily relies on the number and distribution of such resources. The goal of this paper is twofold: first, to design a technique to estimate the steady-state performance of a given system with shared resources, and second, to propose a heuristic strategy to distribute shared resources so that the system performance is enhanced as much as possible. The systems under consideration are assumed to be large systems, such as service-oriented architecture (SOA) systems, and modeled by a particular class of Petri nets (PNs) called process PNs. In order to avoid the state explosion problem inherent to discrete models, the proposed techniques make intensive use of linear programming (LP) problems.},

Abstract = {Performability relates the performance (throughput) and reliability of software systems whose normal behaviour may degrade owing to the existence of faults. These systems, naturally modelled as discrete event systems using shared resources, can incorporate fault-tolerant techniques to mitigate such a degradation. In this article, compositional fault-tolerant models based on Petri nets, which make its sensitive performability analysis easier, are proposed. Besides, two methods to compensate existence of faults are provided: an iterative algorithm to compute the number of extra resources needed, and an integer-linear programming problem that minimises the cost of incrementing resources and/or decrementing fault-tolerant activities. The applicability of the developed methods is shown on a Petri net that models a secure database system.},

Abstract = {Many discrete systems with shared resources from different artificial domains (such as manufacturing, logistics or web services) can be modelled in terms of timed Petri nets. Two studies that may result of interest when dealing with such a systems are the performance evaluation (or completed jobs per unit of time) and the resource optimisation. Exact performance evaluation, however, may become unachievable due to the necessity of an exhaustive exploration of the state-space. In this context, a solution can be to estimate the performance by computing bounds. Resource optimisation leverages a budget and distributes resources in order to maximise the system performance. In this paper, we present PeabraiN, a collection of PIPE tool-compliant modules for performance estimation and resource optimisation based on bounds computation for Stochastic Petri Nets. The algorithms supporting the modules make an intensive use of linear programming techniques and therefore their computational complexity is low. Besides, other PN properties, such as structural enabling bound at a transition, structural marking bound at a place or visit ratios computation, are added to PIPE tool as well.},

Abstract = {Data movement between tasks in scientific workflows has received limited attention compared to task execution. Often the staging of data between tasks is either assumed or the time delay in data transfer is considered to be negligible (compared to task execution). Where data consists of files, such file transfers are accomplished as fast as the network links allow, and once transferred, the files are buffered/stored at their destination. Where a task requires multiple files to execute (from different tasks), it must, however, remain idle until all files are available. Hence, network bandwidth and buffer/storage within a workflow are often not used effectively. We propose an automated workflow structural analysis method for Directed Acyclic Graphs (DAGs) which utilises information from previous workflow executions. The method obtains data-throttling values for the data transfer to enable network bandwidth and buffer/storage capacity to be managed more efficiently. We convert a DAG representation into a Petri net model and analyse the resulting graph using an iterative method to compute data-throttling values. Our approach is demonstrated using the Montage workflow.},

Abstract = {In data intensive workflows, which often involve files, transfer between tasks is typically accomplished as fast as the network links allow, and once transferred, the files are buffered/stored at their destination. Where a task requires multiple files to execute (from different previous tasks), it must remain idle until all files are available. Hence, network bandwidth and buffer/storage within a workflow are often not used effectively. In this paper, we are quantitatively measuring the impact that applying an intelligent data movement policy can have on buffer/storage in comparison with existing approaches. Our main objective is to propose a metric that considers a workflow structure expressed as a Directed Acyclic Graph (DAG), and performance information collected from historical past executions of the considered workflow. This metric is intended for use at the design-stage, to compare various DAG structures and evaluate their potential for optimisation (of network bandwidth and buffer use).},

Abstract = {Security attacks aim to system vulnerabilities that may lead to operational failures. In order to react to attacks software designers use to introduce Fault-Tolerant Techniques (FTTs), such as recovery procedures, and/or Security Mechanisms (SMs), such as encryption of data. FTTs and SMs inevitably consume system resources, hence they influence the system performance, even affecting its full operability. The goal of this paper is to provide a model-based methodology able to quantitatively estimate the performance degradation due to the introduction of FTTs and/or SMs aimed at protecting critical systems. Such a methodology is able to inform software designers about the performance degradation the system may incur, thus supporting them to find appropriate security strategies while meeting performance requirements. This approach has been applied to a case study in the E-commerce domain, whose experimental results demonstrate its effectiveness.},

Abstract = {Software systems that do not meet their timing constraints
can cause risks. In this work we propose a comprehensive
method for assessing the risk of timing failure by evaluating the
software design. We show how to apply best practises in software engineering
and well-known Time Petri Net (TPN) modeling and analysis
techniques, and we demonstrate the effectiveness of the
method with reference to a case study in the domain of realtime
embedded systems. The method customizes the Australian standard risk
management process, where the system context is the UML-based
software specification, enriched with standard MARTE profile
annotations to capture non-functional system properties. During
the risk analysis, a TPN is derived, via model transformation,
from the software design specification and TPN bound techniques
are applied to estimate the probability of timing failure. TPN
bound techniques are also exploited, within the risk evaluation
and treatment steps, to identify the risk causes in the software
design.},

Abstract = {Security is a non-functional property that, at least, should be documented early in the software life-cycle, but also assessed whenever possible in these stages. However, modelling system security is not a common practise in software projects yet and there is not a standard for this purpose. UML, the de facto standard as modelling language, can be tailored for specific purposes through profiling. For example, UML features MARTE, a profile for quantitative analysis of schedulability and performance. Other profile, DAM (which inherits from MARTE) enables UML for quantitative analysis of dependability. Dependability and security share well-known concerns at the core of computing: availability and integrity. In this work, the basis of a security profile for UML is developed. It is built on the MARTE-DAM framework and accounts for the tight relationships between security and dependability. Concretely, access control mechanisms and resilience topic are addressed in this work to establish the main body of the proposed profile. Some examples are used through the paper to illustrate the usage of the profile.}

Abstract = {The adequate system performance is usually a critical requirement to be checked during the verification phase of a system. Thus, accurately measuring the performance of current industrial systems, which are often modelled as a Discrete Event Systems (DES), is a need. Due to the state explosion problem, the performance evaluation of DES becomes increasingly difficult as the size of the systems increases. Some approaches, such as the computation of performance bounds, have been developed to overcome this problem. In this paper we propose a new method to produce performance bounds that are sharper than the ones that can be achieved with current methods. The core of our method is an iterative algorithm that initially considers the most constraining bottleneck cycle of the system and adds other cycles to it in each iteration. The proposed method is deeply explained and then applied to a broad set of Marked Graphs.},

Abstract = {Software designs equipped with specification of dependability techniques can help engineers to develop critical systems. In this work, we start to envision how a software engineer can assess that a given dependability technique is adequate for a given software design, i.e., if the technique, when applied, will cause the system to meet a dependability requirement (e.g., an availability degree). So, the idea here presented is how to integrate already developed fault-tolerant techniques in software designs for their analysis. On the one hand, we will assume software behavioural designs as a set of UML state-charts properly annotated with profiles to take into account its performance, dependability and security characteristics, i.e., those properties that may hamper a critical system. On the other hand, we will propose UML models for well-known fault-tolerant techniques. Then, the challenge is how to combine both (the software design and the FT techniques) to assist the software engineer. We will propose to accomplish it through a formal model, in terms of Petri nets, that offers results early in the life-cycle.},

Abstract = {Modelling system security is not common practise in software projects yet. Among other problems, there is not a widely accepted methodology which unifies the actual heterogeneity of security issues when addressing a whole security specification. Certainly, the reality is even worse since there is not an accepted or standard common notation for carrying out the security specification. In this work, we study how modelling security issues, specifically resilience, could be integrated in the MARTE-DAM framework, which allows the expression of performance and dependability requirements in UML models. We base this claim on the close relationship between security and dependability. Indeed, MARTE proposes a framework for non-functional properties specification (NFP), while DAM exploits it for dependability purposes. So, our goal is to take advantage of the common NFP framework while the dependability and security concerns are modelled in a unified view. On the other hand, we consider that the resulting security specification will be useful for developing model in which security related properties, such as availability, will be analysed. We will clarify these claims by means of an example.},

Abstract = {Time Petri Nets (TPNs) have been widely used for the verification and validation of real-time systems during the software development process. Their quantitative analysis consists in applying enumerative techniques that suffer the well known state space explosion problem. To overcome this problem several methods have been proposed in the literature, that either provide rules to obtain equivalent nets with a reduced state space or avoid the construction of the whole state space. In this paper, we propose a method that consists in computing performance bounds to predict the average operational behavior of TPNs by exploiting their structural properties and by applying operational laws. Performance bound computation was first proposed for Timed (Timed PNs) and Stochastic Petri nets (SPNs). We generalize the results obtained for Timed PNs and SPNs to make the technique applicable to TPNs and their extended stochastic versions: TPN with firing frequency intervals (TPNFs) and Extended TPNs (XTPNs). Finally, we apply the proposed bounding techniques on the case study of a robot-control application taken from the literature.},

Abstract = {A general iterative technique for approximate throughput computation of stochastic live and bounded weighted T-systems is presented. It generalizes a previous technique on stochastic marked graphs. The approach has two basic foundations. First, a deep understanding of the qualitative behaviour of weighted T-systems leads to a general decomposition technique. Second, after the decomposition phase, an iterative response time approximation method is applied for the throughput computation. Existence of convergence points for the iterative approximation method can be proved. Experimental results generally have an error of less than 5%. The state space is usually reduced by more than one order of magnitude; therefore, the analysis of otherwise intractable systems is possible.},

Abstract = {Software performance engineering deals with the consideration of quantitative analysis of the behaviour of software systems from the early development phases in the life cycle. This paper summarizes in a semiformal and illustrative way our proposal for a suitable software performance engineering process. We try to integrate in a very pragmatic approach the usual object oriented methodology ---supported with UML language and widespread CASE tools--- with a performance modelling formalism, namely stochastic Petri nets. A simple case study is used to describe the whole process. More technical details should be looked up in the cited bibliography.},

Abstract = {Software performance engineering (SPE) is proposed as a method for the performance evaluation of software systems early in the development process. The generic approach of the SPE consists of deriving performance models from UML specifications. This paper, following the SPE principles, addresses the UML StateCharts (SCs) and the Sequence Diagrams (SDs) as UML specifications, while performance models are specified with Generalized Stochastic Petri Nets. The proposed derivation, actually the authors interpretation of the SC and SD, provides these two kinds of UML diagrams with a formal semantics. The interpretation is based on the UML semi-formal semantics. A software fault tolerance mechanism is used as an example to illustrate how, following the proposal, the SC and the SD are automatically converted into GSPNs. Another contribution of the work is the consistency study among the SC and the SD, since they are used in a combined manner to obtain the target performance model. The approach presented in this paper allows to derive two kinds of performance models: one representing the behaviour of the whole system and another representing the particular execution described by a SD.}

Abstract = {A general iterative technique for approximate throughput computation of stochastic live and bounded Deterministic Systems of Sequential Processes (DSSPs, a subclass of Petri nets) is presented. It generalizes a previous technique on stochastic weighted T-systems. The approach has two basic foundations. First, a deep understanding of the qualitative behaviour of DSSPs leads to a general decomposition technique. Second, after the decomposition phase, an iterative response time approximation method is applied for the throughput computation. We apply the obtained technique to the performance evaluation of manufacturing systems modelled with Petri nets. Experimental results generally have an error of less than 5 %. The state space is usually reduced by more than one order of magnitude; therefore, the analysis of otherwise intractable systems is possible.}

Abstract = {Interval time Petri Nets are Petri nets in which time intervals are associated to transitions. Their quantitative analysis basically consists in applying enumerative techniques that suffer the well known state space explosion problem. To overcome this problem several methods have been proposed in the literature, that either allow to obtain equivalent nets with a reduced state space or avoid the construction of the whole state space. The alternative method proposed here consists in computing performance bounds to partially characterize the quantitative behavior of interval time Petri Nets by exploiting their structural properties and/or by applying operational laws. The performance bound computation is not a new technique: it has been proposed for timed Petri nets. In this paper we present the results obtained from a preliminary investigation on the applicability of bounding techniques of timed Petri nets to interval time Petri Nets.},

Abstract = {In this paper we address the mobile robot localization using some techniques borrowed from the Computational Biology community. The specific problem studied here is also known as the kidnapped robot problem. Our proposal is to solve this problem by string matching algorithms, which have experienced a large advance in the last years due to (for example) the Genoma Project. The paper uses three different algorithms to solve the mentioned problem and shows their advantages, such as the robustness of the results and the memory and time efficiency. These results are validated by real experimentation using panoramic images of indoor buildings, and compared and discussed with existing techniques that have been used over the same test-bed.},

Abstract = {Over the last decade, the relevance of performance evaluation in the early stages of the software development life-cycle has been steadily rising. We honestly believe that the integration of formal models in the software engineering process is a must, in order to enable the application of well-known, powerful analysis techniques to software models. In previous papers the authors have stated a proposal for SPE, dealing with several UML diagram types.The proposal formalizes their semantics, and provides a method to translate them into (analyzable) GSPN models. This paper focuses on activity diagrams, which had not been dealt with so far. They will be incorporated in our SPE method, enhancing its expressivity by refining abstraction levels in the statechart diagrams. Performance requirements will be annotated according to the UML profile for schedulability, performance and time. Last but not least, our CASE tool prototype will be introduced. This tool deals with every model element from activity diagrams and ensures an automatic translation from ADs into GSPNs strictly following the process related in this paper.},

Abstract = {Software systems are today one of the most complex artifacts, they are simultaneously used by hundred-thousand of people sometimes in risk real time operations, such as auctions or electronic commerce. Nevertheless, it is a common practice to deploy them without the expected performance. Software Performance Engineering has emerged as a discipline to complement Software Engineering research in order to address this kind of problems. In this work, we survey some recent contributions in the field of Software Performance Engineering. The approach surveyed has as main features that it uses the UML diagrams to specify the functional and performance requeriments of the system and the stochastic Petri nets formalism to analyse it.},

Abstract = {It is not an overstatement to say that the gap between software design and performance evaluation techniques has caused the misuse of the last ones by software engineers. The UML profile for schedulability, performance and time arose from the intention to close both fields, software engineering and performance analysis. Nevertheless the gap remains, since it is difficult for software engineers to devise which parts of their designs are suitable to represent performance requirements. The profile has started to study this problem from a scenarios viewpoint. In this work, we explore other viewpoints to deal with performance requirements at software design level.},

Abstract = {Software design and implementation using mobile agents are nowadays involved in a scepticism halo. There are researchers who question its utility because it could be a new technology that does provide new skills but it could introduce new problems. Security and performance are the most critical aspects for this new kind of software. In this paper we present a formal approach to analyse performance for this class of systems, which is integrated in the early stages of the software development process. We propose to model the software system in a pragmatic way using as a design technique the well-known design patterns; from these models, the corresponding formal performance model, in terms of Petri nets, is obtained semi-automatically by applying a set of translation rules. Therefore, the formal performance model is obtained as a by-product of the software life-cycle, preserving the benefits of the software design techniques. Finally, the formal performance model is analysed, using analytical techniques, in order to study the performance of the system. Moreover, another benefit of the proposal is that it is possible to predict the behaviour of the system without the necessity of implementing it. To illustrate the proposal, we apply it to a software retrieval service system designed using mobile agents.},

Abstract = {Nowadays, there exist web sites that allow users to retrieve and install software in an easy way. The performance of these sites may be poor if they are used in wireless networks; the reason is the inadequate use of the net resources that they need. If this kind of systems are designed using mobile agent technology the previous problem might be avoided. In this paper, we present a comparison between the performance of a software retrieval system especially designed to be used in a wireless network and the performance of a software retrieval system similar to the well-known Tucows.com web site. In order to compare performance, we make use of a software performance process enriched with formal techniques. The process has as important features that it uses UML as a design notation and it uses stochastic Petri nets as formal model. Petri nets provide a formal semantics for the system and a performance model.},

Abstract = {Importance of performance evaluation at first stages of the software development life-cycle has been progressively rising. We believe that the need for integration of formal models in the software engineering process is a must in order to apply well-known analysis techniques to software models. In previous papers it has been stated our proposal of extension of UML semantics for some diagram types and a complete method to translate them into GSPN models. Here we will focus on activity diagrams: a new translation method for them will be presented, while we explain their link with other UML diagrams such as statecharts so as to amplify the expressivity at system description. Last but not least, our CASE tool prototype will be introduced. As it will be seen, every modeling aspect for these diagrams will be covered and, thanks to it, the translation process will be automatically performed.},

Abstract = {The increasing relevance of UML as a semi-formal modelling paradigm has entailed the need for an adjustment of the classical performance evaluation methods within the scope of the new working environment. Under these circumstances, a formal semantics for the UML language and a strong mathematical substratum are required in order to be able to compute performance estimates and validate logical properties in the first stages of the software life-cycle. We believe that stochastic Petri nets are specially suited for this aim. A compositional approach for the translation of several UML diagrams into analyzable Petri net models has there fore been considered in previous papers. Following this ap proach, we will focus here in the depiction of a model case study from the perspective of our new performance-oriented CASE tool.},

Abstract = {Unified Modeling Language (UML) is gaining widespread acceptance as an effective way to describe the behaviour of systems. As such it has also attracted the attention of researchers that are interested in deriving, automatically, performance evaluation models from system's descriptions. A required step to automatically produce a performance model (as any executable model) is that the semantics of the description language is formally defined. Among the various models of UML we concentrate on States Machines and we build a semantics for them in terms of Generalized Stochastic Petri Nets, a well established modelling formalism for the performance evaluation of distributed systems. The paper introduces rules that allow to derive from a description of a system, expressed as a set of State Machines, an executable GSPN model. The semantics is compositional since the executable GSPN model is obtained by composing, using standard Petri Net operators, the GSPN models of the single State Machines, and each GSPN model is obtained by composition of submodels for State Machine basic features such as internal and outgoing transitions, states, actions, and events.},

Abstract = {Formal methods are the most suitable way to model and analyze several kinds of software systems. However, conventional methods are gaining placed in Software Engineering field because they can be easily applied in all the stages of the software life cycle. The combination of formal and conventional methods could be an interesting approach to describe and analyze some software aspects, as for example, the performance of the system. In this way, we make use of a software performance process enriched with formal techniques. The process has as important features that it uses UML as a design notation and it uses stochastic Petri nets as formal model. Petri nets provide a formal semantics for the system and a performance model, while UML supplies the framework and tools to document the system. The process is used in this article to present a performance comparison between software retrieval systems. Nowadays, there exist web sites that allow users to retrieve and install software in an easy way. The performance of these sites may be poor if they are used in wireless networks; the reason is the inadequate use of the net resources they need. In this article, we show that if this kind of systems are designed using mobile agent technology the previous problem might be avoided.},

Abstract = {The use of the object-oriented paradigm in the software industry is nowadays a reality. Approximations like frameworks, components, workflows or patterns are gaining place, sometimes to complement object-oriented development. Like the object-oriented paradigm of these approaches make special emphasis on the reuse of the software as a way to increase productivity. But the performance of software systems is not as good as desired. Thus, techniques to predict it are subject of research. Software Performance Engineering is concerned with these problems. Here we present an approach to reuse performance models developed in the early stages of the software development process. The approach has as a goal the use of formal models to predict performance.},

Abstract = {A complementary approach to exact or approximation techniques for the analysis of timed or stochastic Petri net models is the computation of bounds for their performance measures. Performance bounds are useful in the preliminary phases of the design of a system, in which many parameters are not known accurately. Several alternatives for those parameters should be quickly evaluated, and rejected those that are clearly bad. Exact (and even approximate) solutions would be computationally very expensive. Bounds become useful in these instances since they usually require much less computation effort. In this tutorial, net-driven techniques for the computation of bounds for the main performance indices of timed Petri net models are considered. Special attention is given tothe intimate relationship between qualitative and quantitative aspects of Petri nets. In particular, the intensive use of structure theory of net models allows to obtain very efficient computation techniques.},

Abstract = {Asynchronously Communicating Stochastic Modules (SAM) are Petri nets that can be seen as a set of modules that communicate through buffers, so they are not (yet another) Petri net subclass, but they complement a net with a structured view. This paper considers the problem of exploiting the compositionality of the view to generate the state space and to find the steady-state probabilities of a stochastic extension of SAM in a net-driven, efficient way. Essentially, we give an expression of an auxiliary matrix, G, which is a supermatrix of the infinitesimal generator of a SAM. G is a tensor algebra [Davio 1981] expression of matrices of the size of the components for which it is possible to numerically solve the characteristic steady-state solution equation pi.G = 0, without the need to explicitly compute G. Therefore, we obtain a method that computes the steady-state solution of a SAM without ever explicitly computing and storing its infinitesimal generator, and therefore without computing and storing the reachability graph of the system. Some examples of application of the technique are presented and compared to previous approaches.},

Basically, the idea is to represent (or partially represent) in a decomposed manner the reachability graph of the model so it can be used for exact and/or approximated performance analysis. In that way, the complete storing of the graph is avoided and, for the case of approximate analysis, the solution of the isomorphous continuous time Markov chain is substituted by the solution of smaller components. The techniques are applied to a couple of non-trivial models.},

Abstract = {Stochastic Petri nets is a well-known formalism adequate for the design, validation, and performance evaluation of discrete event systems, computer systems, manufacturing systems, telecommunication networks, and so on. In this paper, we deal with three different techniques to decompose the state space of a general stochastic Petri net that can be used to decrease the time and memory requirements of numerical analysis algorithms. The presented techniques are based on the divide and conquer principle to compute from the original model several submodels. These submodels can be used for a functional analysis, structural analysis and performance evaluation (exact and approximate).

Abstract = {A complementary approach to exact or approximation techniques for the analysis of queueing network models is the computation of bounds for their performance measures. Performance bounds are useful in the preliminary phases of the design of a system, in which many parameters are not known accurately. Several alternatives for those parameters should be quickly evaluated, and rejected those that are clearly bad. Exact (and even approximate) solutions would be computationally very expensive. Bounds become useful in these instances since they usually require much less computation effort. In this chapter, we concentrate in net-driven techniques for the computation of bounds for the main performance indices of timed Petri net models. Previous works on bounds computation for classical queueing networks are not included here and the interested reader is referred to the bibliographic remarks in Section 17.5. The presented techniques are characterized by their interest in stressing the intimate relationship between qualitative and quantitative aspects of Petri nets. In particular, the intensive use of structure theory of net models allows to obtain very efficient computation techniques. The organization of the chapter is the following. In Section 17.1, a general approach for the computation of upper and lower bounds for arbitrary linear functions of average marking of places and throughput of transitions of both timed Place/Transition nets and timed Well-Formed Coloured nets is presented. Section 17.2 includes a more intuitive approach for the computation of throughput upper bounds, even if it is valid only for restricted Petri net subclasses. The relation of this technique with the general approach and the attainability of the bound for a particular subclass of nets is included. In Section 17.3, two possible improvements of upper and lower throughput bounds are presented using implicit places and liveness bounds of transitions, respectively. All the bounds computed in Sections 17.1, 17.2 and 17.3 are insensitive to the timing probability distributions since they are based only on the knowledge of the average service times. Section 17.4 includes a brief overview of three additional techniques for the improvement of the bounds. Since some additional assumptions on the form of the probability distribution functions associated to the service of transitions or on the conflict resolution policies are done, the obtained bounds are non-insensitive. Finally, some bibliographic remarks are included in Section 17.5.},

Abstract = {A goal of performance modelling with timed Petri nets (TPN's) is the estimation of some quantifiable performance measures of the system under consideration by the simulation or analysis of the model of the system behaviour. In order to do that, responsiveness and utilization performance measures of the system must be described in terms of average values of operational quantities defined on the TPN model, like the average marking of a place or the firing frequency of a transition. In Section 8.1, the usual average performance indices for TPN models are derived operationally from the basic observable events that were defined in Chapter 3. Sections 8.2 and 8.3 are devoted to exploit the operational approach for the definition of performance measures. In Section 8.2, operational analysis techniques are used to partially characterize the behaviour of TPN models. Classical operational laws, like Little's law are stated in Petri net terms. Additionally, some operational inequalities are derived that are typical of the presence of synchronization and that have not been considered before in the framework of queueing networks models. Section 8.3 illustrates another aspect of the deep gap, from the analytical point of view, existing between classical monoclass product-form queueing networks and TPN's. While in Gordon-Newell networks the vector of visit ratios to the stations can be easily (efficiently) computed from the routing information, in the case of bounded TPN's the computability of such index is a quite complex problem. This problem leads to a classification of net models attending to the dependency of the visit ratios on the net structure and the probabilistic routing, on the initial marking, and on the firing time of transitions. Since few operational analysis techniques can presently be used to compute the performance indices of interest, the classical approach based on stochastic processes must be considered. Section 8.4 introduces also the definition of performance parameters on the TPN model as expected values of the random variables that characterize the behaviour of the model, under some stochastic assumptions. As the reader surely knows, under ergodicity conditions the average (operationally defined) performance indices are equal to the expected (stochastically defined) indices, thus the techniques that will be presented later on for the computation of expected values will be useful to compute the average performance measures of interest. Some bibliographic remarks are summarized in Section 8.5.},

Abstract = {A general iterative technique for approximate throughput computation of strongly connected stochastic marked graphs (SMG's) is presented in this Chapter. We consider SMG's with time and marking independent exponentially distributed service times associated with transitions. The approach has two basic foundations. First, it is deeply based on qualitative theory of MG's. More precisely, given an arbitrary cut (subset of places producing a net partition), a structural decomposition technique is developed that allows us to split a strongly connected MG into two aggregated subsystems and a basic skeleton system. And what is more important, the behaviours of the subsystems, including steps, language of firing sequences and reachable markings, are equivalent to the whole system behaviour (projected on the corresponding subsets of nodes). Second, after the decomposition phase, an iterative response time approximation method is applied for the computation of the throughput. Experimental results on several examples generally have an error of less than 3%. The state space is usually reduced by more than one order of magnitude; therefore the analysis of otherwise intractable systems is possible. The Chapter is organized as follows. In Section 23.1, some fundamental properties on MG's and implicit places are presented. Section 23.2 includes the structural decomposition of MG's used in the rest of the Chapter. The iterative technique for approximate throughput computation is described in Section 23.3. Section 23.4 includes several application examples to illustrate the introduced technique. Finally, some bibliographic remarks are included in Section 23.5.},

Abstract = {Stochastic Petri nets is a well-known formalism adequate for the design, validation, and performance evaluation of discrete event and manufacturing systems. In this paper, we deal with steady-state throughput approximation of complex concurrent systems modelled with stochastic Petri nets. More precisely, we generalize to arbitrary stochastic P/T systems a response time approximation technique that was firstly proposed for special net subclasses. The presented technique is based on the divide and conquer principle and it is achieved in two steps. The first one, a net-driven decomposition of the model into several subsystems and the second one, an iterative solution algorithm that computes a throughput approximation of the original model transitions based on the solution of the embedded continuous time Markov chain of the subsystems. Experimental results on several examples generally have an error of less than 5%, and the state space is usually reduced by more than one order of magnitude.},

Abstract = {As stated in previous chapters, a fundamental question in the use of stochastic Petri net models for performance evaluation, even under Markovian stochastic interpretation, is the so called state explosion problem. A general approach to deal with (computational) complexity is to use a divide and conquer strategy, what requires the definition of a decomposition method and the subsequent composition of partial results to get the full solution. On the other hand, the trade-off between computational cost and accuracy of the solution leads to the use of approximation or bounding techniques (for instance, throughput bounds can be computed in polynomial time on the number of transitions and places, see Chapter 17). In this context, a pragmatic compromise to be handled by the analyzer of a system concerns the definition of faithful models, that may be very complex to exactly analyse (what may lead to the use of approximation or just bounding techniques), or simplified models, for which exact analysis can be, eventually, accomplished. Divide and conquer strategies can be used with exact, approximate, or bounding techniques. The techniques for performance evaluation present in the literature consider either implicit or explicit decomposition of net models. In [7] (see Chapter 17), an implicit decomposition into P-semiflows is used for computing throughput bounds for arbitrary pdf of time durations. In [19] (see Chapter 12), a decomposition into disjoint modules (usually subnets generated by P-semiflows) is defined by the analyzer or provided by model construction; the computational technique uses directly the information provided by the modules to compute exact global limit probability distribution vector. In [8], a decomposition into modules (connected through buffers) should also be provided. In this case, the modules are complemented with an abstract view of their environment in the full model, and the approximate solution is computed through an iterative technique looking for a fixed point (details will be presented in Chapter 23). In the sequel of this Chapter and in a general context, components will refer to (eventually) complemented modules. They are just the elements used to build the full solution. In order to get efficient techniques, the decomposition and, eventually, complementation process should be net-driven (i.e., derived at net level). For this, we shall use PN's structure theory concepts and techniques (e.g., P-semiflows, implicit places, etc.). The Chapter is organised as follows. The main ideas behind net-driven decompositions of PN's are introduced in Section 20.1: the conservative and consistent components (Section 20.1.1), an example of implicit search technique into conservative components (Section 20.1.2), an explicit decomposition of nets, designating the modules to be used (Section 20.1.3), and the complementation of modules to get components (that include information from the environment), using implicit places (Section 20.1.4). A taxonomy for net-driven decomposition techniques is proposed in Section 20.2, providing a framework for the consideration of a significant number of performance evaluation methods. Several representative examples of techniques present in the literature are briefly overviewed and classified according with the classification criteria. Some concluding remarks are included in Section 20.3.},

This paper considers the problem of exploiting this compositionality to generate the state space and to find the steady state probabilities of a stochastic extension of DSSP in a net-driven, efficient way. Essentially, we give an expresion of an auxiliary matrix, G, which is a supermatrix of the infinitesimal generator of a DSSP. G is a tensor algebra expression of matrices of the size of the components for which it is possible to numerically solve the characteristic equation pi.G = 0, without the need to explicitly compute G. Therefore, we obtain a method that computes the steady state solution of a DSSP without ever explicitly computing and storing its infinitesimal generator, and therefore without computing and storing the reachability graph of the system.},

Stochastic weighted T-systems are the weighted extension of well known stochastic marked graphs Petri net subclass and are usually presented as a useful model to deal with bulk consumptions or productions of resources in manufacturing systems working on a cyclic basis. The iterative response time approximation technique that we present is deeply based on a previous structural decomposition and aggregation of the net model. Experimental results on several examples generally have and error of less than 5%. The state space is usually reduced by more than one order of magnitude; therefore, the analysis of otherwise intractable systems is possible.},

It is achieved through the use of a kind of decomposition of the whole net system. Results are obtained deeply bridging stochastic Petri net theory to untimed Petri net and queueing network theories. Previous results are improved by considering some embedded product-form queueing networks (generated by the support of some left annullers of the incidence matrix of the net). The obtained results for the case of live and bounded free choice systems are of special interest. In this case, the subnets generated by the minimal left annullers of the incidence matrix always have a topology of product-form closed monoclass queueing networks.},

Abstract = {Operational analysis is a conceptually very simple way of deriving mathematical equations relating measurable quantities in queueing systems [DB 78]. In [DC 92] the reader can find some nice examples of how the application of operational analysis techniques can help in explaining and proving fundamental results in queueing network analysis. Here we apply operational analysis techniques to derive linear equations and inequalities relating interesting performance measures in timed Petri net models. The main conceptual difference between queueing and Petri net models is the presence of a synchronization primitive in the latter. New operational inequalities are derived for synchronization elements that have no counterpart in operational laws for queueing networks. In addition to the mathematical interest of these derivations, the results can be immediately used for the computation of performance bounds based on linear programming techniques.}

Abstract = {In this paper we present the Local Optimality (LO) property for Discrete Event Dynamic Systems modeled using Petri Nets (PN's). If a system is divided into independent subsystems and if the optimal behaviour of these subsystems guarantees the optimal behaviour of whole system, then this system possesses the LO property. The main advantage of this approach is that we can find an optimal schedule for this class of systems in less time, because we are determining the optimal behaviour of small problems. A characterization of systems exhibiting the LO property is given, as well as one procedure to divide them into subsystems.},

Abstract = {Petri Nets (PNs) is a well suited formalism to model and analyze parallel and distributed discrete event dynamic systems. Provided with adequate timed interpretation, PNs allow to build performance models in which true concurrence can be described together with synchronization and sharing phenomena. This survey paper gives a fast overview of some major topics related to net performance models, obtained through stochastically timed interpretation of PNs. Analysis of net models, pointing out the importance of the logical and performance perspectives, and some relations between queueing networks and PN models are briefly considered.},

Abstract = {A class of synchronized queueing networks with deterministic routing is identified to be equivalent to a subclass of timed Petri nets called marked graphs. First some structural and behavioral properties of marked graphs are recalled and used to show interesting properties of this class of performance models. In particular, ergodicity is derived from boundedness and liveness of the underlying Petri net representation, which can be efficiently computed in polynomial time on the net structure. In case of unbounded (i.e., non-strongly-connected) marked graphs, ergodicity is computed as a function of the average transition firing delays. Then the problem of computing both upper and lower bounds for the steady-state performance of timed and stochastic marked graphs is studied. In particular, linear programming problems defined on the incidence matrix of the underlying Petri nets are used to compute tight (i.e., attainable) bounds for the throughput of transitions for marked graphs with deterministic or stochastic time associated with transitions. These bounds depend on the initial marking and the mean values of the delays but not on the probability distribution functions (thus including both the deterministic and the stochastic cases). The benefits of interleaving qualitative and quantitative analysis of marked graph models are shown.},

Abstract = {In this paper we overview some recent results obtained by the authors and collaborators on the performance bounds analysis of some stochastic Petri net systems. The mathematical model can be seen either as a result of the addition of a particular random timing interpretation to an "autonomous'' Petri net or as a generalization of classical queueing networks with the addendum of a general synchronization primitive. It constitutes an adequate tool for both the validation of logical properties and the evaluation of performance measures of concurrent and distributed systems. Qualitative and quantitative understandings of Petri net models are stressed here making special emphasis on structural techniques for the analysis of logical and performance properties. Important aspects from the performance point of view, such as relative throughput of stations (transitions), and number of servers present at them, are related to Petri net concepts like P- or T-semiflows or liveness bounds of transitions. For the particularly interesting case of Markovian Petri net systems, some improvements of the bounds can be achieved. Marked graphs and free choice are net subclasses for which the obtained results have special quality, therefore an additional attention is focussed on them.},

Abstract = {Several proposals exist for the introduction of synchronization constraints into Queueing Networks (QN). We show that many monoclass QN with synchronizations can naturally be modelled with a subclass of Petri Nets (PN) called Free Choice nets (FC), for which a wide gamut of qualitative behavioural and structural results have been derived. We use some of these net theoretic results to characterize the ergodicity, boundedness and liveness of closed Free Choice Synchronized Queueing Networks (FCSQN). Moreover we define upper and lower throughput bounds based on the mean value of the service times, without any assumption on the probability distributions (thus including both the deterministic and the stochastic cases). We show that monotonicity properties exist between the throughput bounds and the parameters of the model in terms of population and service times. We propose (theoretically polynomial and practically linear complexity) algorithms for the computation of these bounds, based on linear programming problems defined on the incidence matrix of the underlying FC net. Finally, using classical laws from queueing theory, we provide bounds for mean queue lengths and response time.},

Abstract = {Product form queueing networks have long been used for the performance evaluation of computer systems. Their success has been due to their capability of naturally expressing sharing of resources and queueing, that are typical situations of traditional computer systems, as well as to their efficient solution algorithms, of polynomial complexity on the size of the model. Unfortunately, the introduction of synchronization constraints usually destroys the product form solution, so that general concurrent and distributed systems are not easily studied with this class of models. Petri nets have been proved specially adequate to model parallel and distributed systems. Moreover, they have a well-founded theory of analysis that allows to investigate a great number of qualitative properties of the system. In the original definition, Petri nets did not include the notion of time, and tried to model only the logical behaviour of systems by describing the causal relations existing among events. This approach showed its power in the specification and analysis of concurrent systems in a way independent of the concept of time. Nevertheless the introduction of a timing specification is essential if we want to use this class of models for the performance evaluation of distributed systems. One of the main problems in the actual use of timed and stochastic Petri net models for the quantitative evaluation of large systems is the explosion of the computational complexity of the analysis algorithms. In general, exact performance results are obtained from the numerical solution of a continuous time Markov chain, whose dimension is given by the size of the state space of the model. Structural computation of exact performance measures has been possible for some subclasses of nets such as those with state machine topology. These nets, under certain assumptions on the stochastic interpretation are isomorphic to Gordon and Newell's networks, in queueing theory terminology. In the general case, efficient methods for the derivation of performance measures are still needed. Two complementary approaches to the derivation of exact measures for the analysis of distributed systems are the utilization of approximation techniques and the computation of bounds. Approximate values for the performance parameters are in general more efficiently derived than the exact ones. On the other hand, "exactness'' only exists in theory! In other words, numerical algorithms must be applied in practice for the computation of exact values, therefore making errors is inevitable. Performance bounds are useful in the preliminary phases of the design of a system, in which many parameters are not known accurately. Several alternatives for those parameters should be quickly evaluated, and rejected those that are clearly bad. Exact (and even approximate) solutions would be computationally very expensive. Bounds become useful in these instances since they usually require much less computation effort. The computation of upper and lower bounds for the steady-state performance of timed and stochastic Petri nets is considered in this work. In particular, we study the throughput of transitions, defined as the average number of firings per time unit. For this measure we try to compute upper and lower bounds in polynomial time on the size of the net model, by means of proper linear programming problems defined from the incidence matrix of the net (in this sense, we develop structural techniques). These bounds depend only on the mean values and not on the higher moments of the probability distribution functions of the random variables that describe the timing of the system. The independence of the probability distributions can be viewed as a useful generalization of the performance results, since higher moments of the delays are usually unknown for real cases, and difficult to estimate and assess. From a different perspective, the obtained results can be applied to the analysis of queueing networks extended with some synchronization schemes. Monoclass queueing networks can be mapped on stochastic Petri nets. On the other hand, stochastic Petri nets can be interpreted as monoclass queueing networks augmented with synchronization primitives. Concerning the presentation of this manuscript, it should be mentioned that chapter 1 has been written with the object of giving the reader an outline of the stochastic Petri net model: its definition, terminology, basic properties, and related concepts, together with its deep relation with other classic stochastic network models. Chapter 2 is devoted to the presentation of the net subclasses considered in the rest of the work. The classification presented here is quite different from the one which is usual in the framework of Petri nets. The reason lies on the fact that our classification criterion, the computability of visit ratios for transitions, is introduced for the first time in the field of stochastic Petri nets in this work. The significance of that criterion is based on the important role that the visit ratios play in the computation of upper and lower bounds for the performance of the models. Nevertheless, classical important net subclasses are identified here in terms of the computability of their visit ratios from different parameters of the model. Chapter 3 is concerned with the computation of reachable upper and lower bounds for the most restrictive subclass of those presented in chapter 2: marked graphs. The explanation of this fact is easy to understand. The more simple is the model the more accessible will be the techniques an ideas for the development of good results. Chapter 4 provides a generalization for live and bounded free choice nets of the results presented in the previous chapter. Quality of obtained bounds is similar to that for strongly connected marked graphs: throughput lower bounds are reachable for bounded nets while upper bounds are reachable for 1-bounded nets. Chapter 5 considers the extension to other net subclasses, like mono-T-semiflow nets, FRT-nets, totally open deterministic systems of sequential processes, and persistent nets. The results are of diverse colours. For mono-T-semiflow nets and, therefore, for general FRT-nets, it is not possible (so far) to obtain reachable throughput bounds. On the other hand, for bounded ordinary persistent nets, tight throughput upper bounds are derived. Moreover, in the case of totally open deterministic systems of sequential processes the exact steady-state performance measures can be computed in polynomial time on the net size. In chapter 6 bounds for other interesting performance measures are derived from throughput bounds and from classical queueing theory laws. After that, we explore the introduction of more information from the probability distribution functions of service times in order to improve the bounds. In particular, for Coxian service delay of transitions it is possible to improve the throughput upper bounds of previous chapters which held for more general forms of distribution functions. This improvement shows to be specially fruitful for live and bounded free choice nets. Chapter 7 is devoted to case studies. Several examples taken from literature in the fields of distributed computing systems and manufacturing systems are modelled by means of stochastic Petri nets and evaluated using the techniques developed in previous chapters. Finally, some concluding remarks and considerations on possible extensions of the work are presented.},

Abstract = {Steady-state performance evaluation of some repetitive automated manufacturing systems modelled by means of stochastic or deterministic timed Petri nets is considered. Basically, concepts and techniques developed by the authors in other works are applied to repetitive manufacturing systems in this paper. Linear programming problems defined on the incidence matrix of the underlying Petri nets are used to compute tight upper and lower bounds for the performance measures of job-shop systems and decision-free kanban systems in polynomial time on the net structure. The results can be extended to other models in which some decisions are allowed, such as producer-consumer systems with mutual exclusion. Exact performance measures for a class of systems containing sequential processes can be computed in polynomial time.},

Abstract = {Proving properties of Place/Transition Nets through Linear Algebraic Techniques is very interesting because of the polynomial complexity of the algorithms used for this purpose. In this sense, many works have been devoted to the linear analysis of marking related properties (e.g. boundedness of the state space, mutual exclusions, etc.). Nevertheless, few results exist related to linear analysis of liveness properties. In this note, we investigate some applications of linear techniques to partial characterization of liveness properties. First, a necessary condition for structural liveness in structural bounded nets is presented. It is based on the rank of the incidence matrix. Finally, given an initial marking, some sufficient conditions for dead transitions and for deadlock-freeness are presented.},
