Performance modelling of complex dynamic production systems using temporised object-oriented Petri nets with changeable structure (TOPNs-CS)

An object-oriented Petri net with changeable structure (OPN-CS) is capable of modelling complex dynamic production systems subject to changes. However , an OPN-CS is limited to functionality modelling of the system. For perfor mance modelling of a complex dynamic production system, OPNs-CS are extende d to temporised OPNs-CS (TOPNs-CS). The extension is carried out by tempori sing OPNs of production resources and the message passing relationships amo ng production resources. The methods of capturing some performance propriet ies based on a TOPN-CS model of a system are presented. A case study is pro vided to show how TCPN-CS is used for modelling complex dynamic production systems. TOPNs-CS can be applied in control, scheduling, and optimisation o f the processes of a dynamic production system subject to changes.
