Product development (PD) process modeling has been a critical problem in modern PD process management. First we discuss the many benefits of PD process modeling, and then we outline the characteristics of PD pattern in order to provide a full and exact description of it. A powerful modeling language is introduced which is based on the characteristics of modern PD and Hierarchical Timed Colored Petri Nets (HTCPN). A pump development process model based on HTCPN is proposed. The performance analysis of HTCPN and the HTCPN-based process model are presented. Various performance measures of PD process can be generated from the proposed model.
