Temporized coloured Petri nets with changeable structure (CPN-CS) for performance modelling of dynamic production systems

One of the difficulties in modelling dynamic production systems is the repr esentation of changes to the system along time. Coloured Petri nets with ch angeable structure (CPN-CS) are capable of modelling systems subject to cha nge. However, this is restricted to functionality modelling of the system. In this paper, we extend CPN-CSs into temporized CPN-CS (TCPN-CS). The exte nsion is carried out by associating relevant modelling elements with time p arameters and modifying the mechanism for structure change of the CPN-CS mo del. TCPN-CS makes it possible to model a dynamic production system conside ring both functionality and performance. A case study is provided to show t hat TCPN-CS is effective for modelling dynamic production systems.
