Application of Stochastic Petri Net to System Availability Analysis

Since presented in 1962, Petri Net is generally focused by academy and industry. In this paper, the application of stochastic Petri net on system availability analysis is mainly discussed. With the beginning of the basic concepts and models of Petri net, stochastic Petri net (SPN), general stochastic Petri net (GSPN) and stochastic reward model (SRN) are illustrated. The application of stochastic Petri net on system availability analysis and analysis of stochastic Petri net model is discussed with the example of standby systems. In the end, the advantages of using stochasticPetri net to model a practical system are discussed comparing to other modeling methods.
