摘要

Petri nets are presented as a technique for representing computer systems having asynchronous, concurrent operations. The structure of the nets are analyzed as a means of demonstrating the correctness of the modeled system. The execution of the petri net is considered as a stochastic process, allowing analysis of the model as a queueing network system by transforming the petri net into its stochastic equivalent net. It is shown that product form solutions for the state probabilities exist for the class of state machine decomposable nets but not for the more general class of consistent petri nets. Solutions for the corresponding open systems are derived by extending the petri net model to include arbitrary sources and sinks. (Author)
