A scheme is obtained using synthesis of Petri nets shared subnet, according to design and analysis of flexible manufacturing system. Dynamic property preservations of the synthesis net have been investigated. A group of sufficient conditions of liveness preservation, boundedness preservation are presented. A flexible manufacturing system has been designed and analyzed. These results are useful for studying the static and dynamic properties of Petri nets and analyzing properties for large complex system. The synthesis method is especially fit for flexible manufacturing system design and practical to use in reality.
