A framework for hybrid modeling/simulation of discrete event systems

This paper presents a hybrid modeling/simulation framework within which both accuracy in models and speed in simulation experimentations are obtained. Based on the Zeigler's DEVS formalism and associated system theory, the framework is based on the transformation of selected DEVS model into equivalent analytic ones to simulate both analytic and simulation models within a single environment. For high-speed hybrid simulation, the authors extended DEVSim++ which is a realization of the DEVS formalism in C++. To exemplify the proposed approach, the authors demonstrate performance modeling and simulation of a simple communication network.>
