Indirect Modeling Method by Translating IDEF0 Model into Petri Net Model

Characteristics of IDEF0 modeling method and Petri net method were analyzed and compared.An IDEF0 model is non-dynamic and incomplete,and current IDEF system serial methods are not uniform so that the system developing processes are divided into many separate ones.These problems can be overcome by modeling complete system using Petri net.The principle and basic method to translate an IDEF0 model into Petri net model was proposed.As an example,an information management module was translated successfully.Some key technologies to improve the basic method were discussed.The research helps to develop system by unified Petri net method,and provides a new way to solve current problems.
