STOCHASTIC OBJECT-ORIENTED PETRI NETS (SOPNS) AND ITS
APPLICATION IN MODELING
OF MANUFACTURING SYSTEM
RELIABILITY*
Abstract: Object-oriented Petri nets (OPNs) is extended into stochastic object-oriented Petri nets (SOPNs) by associating the OPN of an object with stochastic transitions and introducing stochastic places. The stochastic transition of the SOPNs of a production resources can be used to model its reliability, while the SOPN of a production resource can describe its performance with reliability considered. The SOPN model of a case production system is built to illustrate the relationship between the system’s performances and the failures of individual production resources.
