摘要
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。
In the beginning, virtual enterprise and VIPD, and the urgency in applying VIPD in national aviation industry, are described. Next, by analyzing the architecture and its limitation of the typical distributed VIPD are sum up, and a viewpoint for applying central control is proposed. As a result, a distributed integrated architecture with a central coordinator is given and its mechanism is illustrated. In the end, some key technologies about the architecture, such as integration of polymorphous PDMs, Internet in VIPD, and O-O modeling of global knowledge database, are discussed.
