Implementation and Analysis of DEVS Activity-Tracking with DEVSimPy
Résumé
This paper deals with the implementation of Activity-Tracking (AT) paradigmin the DEVSimPy environment. DEVSimPy has been developed at the SPE UMR CNRS6134 (University of Corsica) in order to facilitate the modeling and the simulation ofdiscrete-event systems described with the DEVS formalism. The AT paradigm is increasinglybeing used by DEVS modelers for example to improve structural aspects ofmodels (modeling level) or to make simulation more ecient using distributed or parallelalgorithm (simulation level). Although DEVSimPy can be used as a software providingsome features reusable for the implementation of AT paradigm (simulation profiling orstep-by-step simulation), the object oriented way used to develop DEVSimPy makes it apowerful tool to implement AT paradigm in a generic manner. DEVSimPy may be viewedas an experimental framework allowing the implementation of new AT techniques whileopening up new perspectives in the field of activity modeling and simulation theory.
