Abstract: Generalized stochastic Petri nets (GSPNs) allow easy modeling of processes in flexible manufacturing systems (FMSs). Due to the rich possibilities of this modeling concept, performance aspects and failure in this kind of systems can be investigated. Depending upon the goal of analysis, pure performance or performance combined with availability, the evaluation procedure of the generalized stochastic Petri net has to be carefully chosen to get trustworthy results. Two models of an FMS, where one shows loss of machines, will be used to discuss the problems of a correct evaluation.
Keywords: flexible manufacturing systems, performability evaluation, performance evaluation, stochastic Petri nets.
