Ph.D. Member



Ingeniero Industrial-Químico by the Universidad de Sevilla (US, 1974), and Ingénieur Automaticien by the Institut National Polytechnique de Grenoble (INPG, 1975), is Docteur Ingénieur by the INPG (1978) and Doctor Ingeniero Industrial by the U. de Sevilla (1979). Since 1981 is full professor of Systems Engineering and Automatic Control at the Universidad de Zaragoza (UZ). Founder of the Systems Engineering and Computer Science Group (the predecessor of the current Department of Computer Science and Systems Engineering), is the director of the GISED (Grupo de Ingeniería de Sistemas de Eventos Discretos), recognised by the Government of Aragón as Group of Excellence in Research, part of the Instituto de Investigación en Ingeniería de Aragón (I3A, 


Vice Dean (1981-86) and Dean (1987-89) of the Zaragoza University School of Industrial Engineering, he drive its transformation into the Polytechnic Centre (CPS) and was its first Director (1989-93). During this period, Telecommunications Engineering (1989) and Computer Engineering (1992) degrees were incorporated into the CPS; and the preparation was done to incorporate Chemical Engineering as well (1994). Also during this period, the following postgraduate courses were implemented: Computer Science (1988), Food Processes Engineering (1988), Bioengineering (1988), Environmental Engineering (1990) and Industrial Organization (1990).


He was President of the Advisory Council for Research (CONAI) of the Research Council of the Aragonese Government (1993-95) and President of the Research and Technological Innovation Committee of the CTP (Comunidad de Trabajo de los Pirineos - Pyrenees Work Group, formed by several regions of France and Spain, and Andorra, 1994-96). He also contributed to the Aragonese Institute for Advancement (IAF) in the creation of new enterprises and technological innovation. Is President of the European Program of Stays for Research (Government of Aragón and Caja Inmaculada).


Author or co-author of some three hundred publications, among his scientific-technical books we can highlight Petri Nets in Automatic Control and Computer Engineering (Ed. AC, Madrid, 1985; republished by Thomson-AC, Madrid, 2002), which introduced the formalism of Petri Nets in Spain.


His preferred engineering area of research is that of Discrete Event Systems (DES), more recently Hybrid Systems also. Basically within the framework of the Petri Nets (PN) paradigm, works on questions as preliminary conception, performance evaluation, implementation issues, control and supervision. Applications concern manufacturing, logistic, software or workflow systems. Last decade is mainly focused on fluid approximations of highly loaded or high cadence discrete event dynamic systems.


Formerly he was also conducting research in robotics, particularly in control and robot programming. From this activity derives the RoPeRT (Robotics, Perception and Real Time Group, He contributed to the creation of the International Fair of Robotics (within the Feria Oficial y Nacional de Muestras de Zaragoza), being the Coordinator of the Technical Workshops (courses and seminars), from the first edition (1984), until 1990.


He has contributed to the organization of close to two hundred international conferences. Member of the Steering Committees of several international conferences (in particular of the International Conferences on Application and Theory of Petri Nets and Other Models of Concurrency, ICATPN and of the IFAC International Conference on the Analysis and Design of Hybrid Systems, ADHS; also past chair of the Steering Committee of the International Workshop on Discrete Event Systems, WODES), he has been working with, or belongs, to the editorial board of several international journals.


He has been coordinator or editor of several books on education and research management (in Spanish), such as Socio-economic Impact of the Expansion of the CPS (1993), in cooperation with the Aragonese Entrepreneurs Confederation (CREA) and the Aragonese Institute of development (IAF); Engineers for a New Century: Objectives of the CPS (1993); A Decade of Research Policy in Aragón (1995); and The Europe Program for Research (CAI-CONAI, 2003).


Interested by History of Science, Technology and Engineering, he is author of the book Uniforms and Emblems of Spanish Civil Engineering, 1835-1975 (Institución Fernando el Católico, DPZ/CSIC, 1999). He was also co-director of CAI-100 (1998- 2001), a collection of 100 pocketbooks aiming to spread the culture of Aragón. This collection includes volumes devoted to economy, science, engineering, and the subsequent heritage. (During the year 2000, CAI-100 received the award of the Aragonese Association of Friends of Books, and was elected Aragonese of the Year in Culture, by the newspaper El Periódico.)


Director of a series of high-level courses devoted to broad research and synthesis perspectives on Technology and Engineering in Spain is the editor of the first encyclopaedia devoted to the topic. At present six volumes has been published (I-Renaissance; II & III-Enlightenment; IV, V & VI Nineteen Century; moreover, the volume devoted to the Renaissance enjoy of a second and enlarged edition in 2008), and some additional four (one more devoted to the XIX century) are planned at present. This work –more than 6.000 pages till now– is published by a consortium formed by the Real Academia de Ingeniería (, the Institución Fernando el Católico ( and Prensas Universitarias de Zaragoza (


He has received a Medal from the City of Lille (France, 1996), and was elected to the Spanish Royal Academy of Engineering (2000). He has received the award to the Contribution to the Development of Telecommunication Engineering in Aragón, from the Telecommunications Engineering Association and the Polytechnic Centre of the University of Zaragoza (2001). Prof. Manuel Silva is Doctor Honoris Causa by the Université de Reims, Champagne-Ardennes (France, 2005).

Ingeniería y Universidad. Sobre dos rememoraciones y un ámbito de investigación pluridisciplinar


Universidad de Zaragoza, Lección Inaugural del curso 2006-2007




Uniformes y Emblemas de la Ingeniería Civil Española, 1835-1975


Institución «Fernando el Católico», Anejos de Emblemata, Zaragoza, 1999


Uniformes, emblemas, banderas y estandartes, himnos, advocaciones religiosas, se emplean como distintivos para denotar pertenencia a un cierto colectivo social. Distintivos de muy variada naturaleza y objeto son profusamente usados en ámbitos como el institucional, el empresarial, el deportivo, el musical, el académico, el religioso y el gastronómico. En las esferas profesionales también se han empleado y se emplean distintivos. La obra pasa revista a uniformes y emblemas de la Ingeniería en España, con un cierto énfasis en lo que atañe a la emblemática de la ingeniería industrial.




Que el presentido como difícil 2016 venga cargado de felicidad




Que en 2017 los hados nos sean favorables


Que en 2018 Fortuna sea benévola



Felices días y esplendoroso 2019



Que en 2020 la realidad supere las mejores predicciones



Que los hados nos sean propicios en el nuevo año
