DEVS today: recent advances in discrete event-based information technology

The DEVS modeling and simulation framework its fundamental concepts are discussed from the standpoint of discrete event information processing with an example drawn from recent experiments on infant cognition is reviewed. 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.
