介绍了动态联盟和VIPD的概念以及我国航空业实施VIPD研究的迫切性。通过对典型VIPD分布式体系结构的分析,总结了分布式结构的局限性并提出集中管理在VIPD中的可行性。在此基础上,给出一种带有中央协调器的分布式集成体系,并阐述了它的工作原理。最后,对该模式涉及的异构PDM集成进行了分析,详细讨论了Internet技术在其中的应用,并初步研究了中央知识库的面向对象建模理论。 Introduced the concept of dynamic alliance and VIPD and the urgency of carrying out VIPD research in China’s aviation industry. Through the analysis of typical VIPD distributed architecture, this paper summarizes the limitations of distributed architecture and puts forward the feasibility of centralized management in VIPD. On this basis, a distributed integrated system with a central coordinator is given, and its working principle is illustrated. Finally, the heterogeneous PDM integration involved in this model is analyzed, the application of Internet technology is discussed in detail, and the object-oriented modeling theory of the central repository is preliminary studied.
