Study And Development Of The Complex Surface Part-Oriented PDM System

The importance of synthetical information platform for virtual enterprise is increasingly recognized. However, existing ERP and PDM do not address the issue of integrating heterogeneous, autonomous, and distributed information with each other, especially for virtual enterprises. This paper proposes the concept of virtual enterprise oriented generalized product management (GPDM) system, which is a new system that optimize and expand ERP and PDM function. This system can serve for virtual enterprise as a synthetical information platform. Further, based on extensible markup language web service (XML Web service), the architecture and function models of GPDM are proposed. Some representative characteristic and pivotal technology of GPDM are analyzed.Mould manufacture is one of the most representative manufactures. This paper analyse the character of the mould manufacture, futher, based on this character and the basic theory of GPDM, the complex surface part-oriented PDM system is proposed. A prototype system has been implemented to demonstrate the feasibility of the proposed architecture.
