Abstract

Generalized stochastic Petri nets (GSPN) and performance evaluation process algebra (PEPA) can both be used to study qualitative and quantitative behaviour of systems in a single environment. The paper presents a comparison of the two formalisms in terms of the facilities that they provide to the modeller; considering both the definition and the analysis of the performance model. Our goal is to provide a better understanding of both formalisms; and to prepare a fertile ground for exchanging ideas and techniques between the two. To illustrate similarities and differences, we make the different issues more concrete by means of an example modelling resource contention.
