'PSA-SPN' – A Parameter Sensitivity Analysis Method Using Stochastic Petri Nets:Application to a Production Line System

摘要

The dynamic behavior of a discrete event dynamic system can be significantly affected forsome uncertain changes in its decision parameters. So, parameter sensitivity analysis would be a usefulway in studying the effects of these changes on the system performance. In the past, the sensitivityanalysis approaches are frequently based on simulation models. In recent years, formal methods based onstochastic process including Markov process are proposed in the literature. In this paper, we areinterested in the parameter sensitivity analysis of discrete event dynamic systems by using stochasticPetri nets models as a tool for modelling and performance evaluation. A sensitivity analysis approachbased on stochastic Petri nets, called PSA-SPN method, will be proposed with an application to aproduction line system.
