Abstract

Modeling and Simulation (M&S) has traditionally been regarded as a tool to support investigation of complex phenomena and systems, not an object of theory in itself. However, this view has been overtaken by the emergence of M&S as a ubiquitous infrastructure, a cohesive community of practice, an identifiable industry, and a challenging educational discipline. A rigorous theoretical basis for M&S is fast becoming an absolute necessity in the face of the rapidly increasing complexity of natural systems being tackled and technological systems being built. This keynote talk highlights the role of the DEVS (Discrete Event Systems Specification) formalism in a constructive framework and systems theory for M&S. I discuss three areas where DEVS theory is making it possible to do things that would not be possible otherwise: automated test generation for net-centric services, verifiably correct parallel and distributed simulation of ultra-large scale networks, and high-resolution modeling and efficient simulation of mixed discrete/continuous heterogeneously composed natural systems.

Bio. of Prof. Bernard P. Zeigler

Bernard P. Zeigler is Professor of Electrical and Computer Engineering at the University of Arizona, Tucson and co-Director of the Arizona Center for Integrative Modeling and Simulation. He is internationally known for his 1976 foundational text Theory of Modeling and Simulation, revised for a second edition (Academic Press, 2000), He has published numerous books and research publications on the Discrete Event System Specification (DEVS) formalism. In 1995, he was named Fellow of the IEEE in recognition of his contributions to the theory of discrete event simulation. In 2000 he received the McLeod Founder's Award by the Society for Computer Simulation, its highest recognition, for his contributions to discrete event simulation. From 2002 to 2004, he served as President of the Society (renamed The Society for Modeling and Simulation, International.) He has served as editor-in-chief of Simulation: Transactions of the SCS and is currently editor-in-chief of the Journal of Defense Modeling and Simulation. Zeigler served on two National Research Council committees to recommend directions for information technology and simulation modeling in the 21st Century and a third NRC committee that was the first to recommend the development of an M&S infrastructure for defense systems acquisition (now being realized as the DoD Net-Centric Enterprise Services). He is currently leading ACIMS projects with the Joint Interoperability Test Command (JITC) in automated generation of distributed simulation-based testing, model-based data engineering, and JITC's testing of Net-centric Enterprise Services.
