Queueing Petri nets are a powerful formalism that can be exploited for modeling distributed systems and analyzing their performance and scalability. However, currently available tools for modeling and analysis using queueing Petri nets are very limited in terms of the scalability of the analysis algorithms they provide. Moreover, tools are available only on highly specialized platforms unaccessible to most potential users. In this paper, we present QPME - a Queueing Petri Net Modeling Environment that supports the modeling and analysis of systems using queueing Petri nets. QPME runs on a wide range of platforms and provides a powerful simulation engine that can be used to analyze models of realistically-sized systems.
