System Developing Method on Unified Petri Net Model

Different methods and models are adapted in current system developing processes;this brings problems such as non-inheritance and non-consistency. To solve these problems,a Petri net method was presented. On the basis of current subnet researches,the problem that how to keep the interface unchanged and reserve original specialties during the transition was discussed. The new methods of analyzing system data and functions were proposed,the idea of clustering algorithm was introduced to divide subsystems automatically. Characteristics of IDEF0 modeling method and Petri net method were analyzed and compared;the principle and basic method to translate an IDEF0 model into Petri net model were presented. The Petri net based system developing method helps to solve problems met in current system developing processes.
