Abstract: Performance analysis of Petri net models is limited by state explosion in the underlying Markovian model. To overcome this problem, an iterative approximate technique is outlined, using a number of auxiliary models, each of much lover state complexity. It is demonstrated on a substantial model which represents a parallel implementation of tow layers of protocols for data communications. The model represents ten separate software tasks and their interactions via rendezvous, and is based on a testbed implementation in the laboratory. Submodels can be constructed in various ways, and this is illustrated with four different decompositions. Their state space complexity , solution time and solution accuracy are evaluated.
