Fuzzy Discrete-Event Systems Modeling and Simulation with Fuzzy Control Language and DEVS Formalism
Résumé
There is an increasing use of fuzzy data in the fieldof discrete-event system modeling. This paper deals with anapproach based on the use of Fuzzy Control Language (FCL)allowing to facilitate the modeling and simulation of DiscreteEVent Systems (DEVS) involving uncertainty. The main contributionof this paper is to integrate the Fuzzy Control Logic threebasic steps (fuzzification, defuzzification, fuzzy rules) into DEVSmodels in a generic way using a FCL-based implementation. Theimplementation has been performed with the DEVSimPy environmentthrough a classical example. The DEVSimPy modelingof the example highlights how the DEVS modeler can realize thethree basic steps inside the DEVS transition functions.
