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.<>
