Bernard P. Zeigler is Professor of Electrical and Computer Engineering at the University of Arizona, Tucson and Director of the Arizona Center for Integrative Modeling and Simulation. He is internationally known for his 1976 foundational text Theory of Modeling and Simulation, recently 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. In June 2002, he was elected President of the Society (recently, renamed The Society for Modeling and Simulation, International.) In 2003, his autobiographical retrospective on the evolution of the theory of modeling and simulation appeared in the International Journal of General Systems. (Vol. 32 (3)).

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 developed a book of recommendations on simulation enhancements to systems acquisition and manufacturing. He has given numerous keynote talks, tutorials and short courses, and organized symposia and conferences that were the first to promote modeling and simulation fundamentals and theory and has been a participant in recent workshops on the science of simulation.

In 2001, with Hessam Sarjoughian and other faculty, he founded the Arizona Center for Integrative Modeling and Simulation dedicated to the development of modeling and simulation as a discipline of the future.

Zeigler currently heads a major ACIMS research and development project with the Joint Interoperability Test Command (JITC) where he is leading the design of the future architecture for large distributed simulation events for the Joint Distributed Engineering Plant (JDEP). He is also developing DEVS-methodology approaches for testing system-of-systems interoperability and combat effectiveness of new major Defense Department acquisitions such as Future Combat System.

Lecture Topics

Simulation-based testing of Emerging Defense Information Systems

Modeling and simulation methodology is attaining core-technology status for standards conformance testing of information technology-based defense systems. To illustrate, we will discuss the development of automated test case generators for testing new defense systems for conformance to military tactical data link standards. In particular, the DEVS discrete event simulation formalism has proved capable of capturing the information-processing complexities underlying the MIL-STD-6016C standard for message exchange and collaboration among diverse radar sensors. We discuss how the formalism is being in distributed simulation to evaluate the performance of an emerging approach to the formation of single integrated air pictures (SIAP).


DEVS Today: Recent Advances in Discrete Event-Based Information Technology

We review the DEVS modeling and simulationframework its fundamental concepts are discussedfrom the standpoint of discrete event informationprocessing with an example drawn from recentexperiments on infant cognition. We also cover the DEVS formalism’s atomic and coupled models and its hierarchical, modular composition approach. Some industrial applications of the methodology are discussed in depth to highlight the formalism’s utility in the development of commercial and defense information technologies.
