Abstract: One of the difficulties in modeling dynamic production systems is the representation if changes to the system along time. Colored Petri nets with changeable structure (CPN-CS) are capable of modeling system subject to change. However, this is restricted to modeling functionality of the system. This paper extends CPN-CS into temporized CPN-CS (TCPN-CS). The extension is carried out by associating relevant modeling elements with time parameters and modifying the mechanism for structure change of the CPN-CS model. TCPN-CS makes it possible to model a dynamic production system considering both functionality and performance. A case study is provided to show that TCPN-CS is effective for modeling dynamic production systems.
