支持网络制造的产品数据管理技术

The research on PDM system technology based on distributed networked-manufacturing

分析了分布式网络化制造系统中企业级之间的产品数据交互和共享问题,对产品数据模型的建立与数据交互技术进行了研究.通过对产品数据管理系统需求的分析,给出了基于公共对象请求代理体系结构的企业级产品数据管理模型,采用对象引用操作与对象适配器技术给出了实体对象实现与引用的方法.

We present a PDM system which supports the enterprise-wide access to product structure data through the World-wide web （WWW）. To meet the needs of various enterprises and types of user, the system is based on a product data model which is both flexible and extensible, The system is implemented using the Object Management Group （OMG） object-oriented database management system and using a Common Object Request Broker Architecture （CORBA） Query Service to access produce data that are in heterogeneous environment. This project deals mainly with extensions of the existing Product Data Management （PDM） system to the distributed networked-manufacturing system.
