• Title: Modeling and Simulation of Generalized Stochastic Discrete Event Systems

• Speaker

Rodrigo Castro, Universidad Nacional de Rosario, Argentina

• Abstract

The DEVS formalism is a general system theoretic based formalism that can represent all the systems whose input/output behavior can be described by sequences of events. Nevertheless, DEVS has only been defined formally for deterministic systems, which limits the stochastic treatment of the systems under study.

In this seminar, we will introduce an extension of the classic DEVS formalism that includes stochastic features. Based on the use of Probability Spaces, the STochastic DEVS specification (STDEVS) provides a formal framework for modeling and simulation of generalized non deterministic discrete event systems. We will go through the main theoretical properties of STDEVS and illustrate its use in a stochastic oriented simulation example with the main purpose of performance analysis in computer systems and data networks.
