The tutorial is divided into three parts. The first part illustrates the main theoretical results. The second part gives an overview of a software tool-the PEPA Eclipse Plug-in-which supports the differential analysis of PEPA. In the last part, this approach is related to other efficient analysis techniques in the literature. In particular, a comparison against layered queues is presented. ID - eprints2574 EP - 307 ER -
