Abstract :
Although generalized stochastic Petri nets (GSPNs) are restricted to only immediate and exponential transitions, they are used for performance analysis of a variety of systems. Flexible manufacturing systems (FMSs) typically contain nonexponential state transitions. GSPN models developed for FMSs present a concern that the above restriction limits the accuracy of performance results. Throughput subnets and s-transitions are introduced. These GSPN constructs allow nonexponential state transitions in a system to be accurately modeled within a GSPN. A GSPN performance model for an FMS example is developed using s-transitions. This system had been previously analyzed using probability theory. Performance analysis results are compared
