Synopsis:
Although twenty-five years have passed since the first edition of this
classical text, the world has seen many advances in modeling and
simulation, the need for a widely accepted framework and theoretical
foundation is even more necessary today. Methods of modeling and
simulation are fragmented across disciplines making it difficult to
re-use ideas from other disciplines and work collaboratively in multi
disciplinary teams. Model building and simulation has been made easier
and faster by riding piggyback on advances in software and hardware.
However, difficult and fundamental issues such as model credibility and
interoperation have received less attention. These issues are now front
and center under the impetus of the High Level Architecture (HLA)
standard mandated by the U.S. DoD for all contractors and agencies.
This book concentrates on integrating the continuous and
discrete paradigms for modeling and simulation. A second major theme is
that of distributed simulation and its potential to support the
co-existence of multiple formalisms in multiple model components.
Prominent throughout are the fundamental concepts of modular and
hierarchical model composition. These key ideas underlie a sound
methodology for construction of complex system models.
This edition presents a rigorous mathematical foundation
for modeling and simulation. Also, it now provides a comprehensive
framework for integrating the various simulation approaches employed in
practice. Including such popular modeling methods as cellular automata,
chaotic systems, hierarchical block diagrams, and Petri Nets. A
unifying concept, called the DEVS Bus, enables models, as expressed in
their native formalisms, to be transparently mapped into the Discrete
Event System Specification (DEVS). The book shows how to construct
computationally efficient, object-oriented simulations of DEVS models
on parallel and distributed environments. If you are doing integrative
simulations, whether or not they are HLA compliant, this is the only
book available to provide the foundation to understand, simplify and
successfully accomplish your task. |
