Introduction to Iterative System Computational Foundations and Devs

Theory of Modeling and Simulation: Discrete Event & Iterative System Computational Foundations (Third Edition) follows its predecessors in providing an authoritative and complete theoretical solution for researchers, graduate students and working engineers interested in posing and solving problems using the tools of computational modeling and simulation. We discuss its main unifying concept, the iterative systems specification, that enables models at any level of structure or behavior, to be transparently mapped into the Discrete Event System Specification (DEVS) formalism. Emphasizing the integration of discrete event and continuous modeling approaches, iterative systems specification provides a sound system-theoretic basis for quantized system and distributed co-simulation supporting the co-existence of multiple formalisms in model components. This introductory exposition emphasizes basic intuitive concepts rather than theorems and proofs that support them. As a running example, we apply the iterative systems formalism to bridging the cognitive behavior to neural circuits gap.
