Generalized Stochastic Petri Nets in Performance Evaluation for Queueing Networks
Mihaela-Hanako Matcovschi, Cristian Mahulea · 2003
Markovian queueing networks may be modeled by generalized stochastic Petri nets. The simulation of a model in a properly chosen simulator provides information on the performances of the actual system, mainly in case that the analytical study is intricate. After presenting some general notions on queueing networks and on generalized stochastic Petri nets, this paper points out the PN Toolbox for MATLAB, an instrument for modeling and simulating several types of Petri nets. The comparison of results obtained through simulation to the analytical ones for a certain model prove the usefulness of this software package for performance evaluation.
