面向PDM的工作流系统研究

A PDM System Oriented Toward Logics Integration

通过归纳与总结PDM系统中信息集成方面的技术特点,提出了过程数据与应用数据的概念;针对PDM系统中过程集成方面的技术特点,从过程开展的角度对其生命周期进行了阶段划分.在此基础上,构造了一个面向数据逻辑与应用逻辑集成的PDM系统框架结构,分析了该框架结构的关键技术.

By summarizing the PDM＇s characteristic technologies in information integration, two concepts of application data and process data are presented. Furthermore, the PDM＇s characteristic technologies in process integration are analyzed and the life cycle of processes is labeled from three stages. Accordingly,a PDM framework is structured oriented toward logics integration between data logic and process logic. The key technologies are pointed out against the framework.
