PROMANS系统中数据管理设计与实现

目的 研究产品数据模型在产品数据管理和并行工程中的应用。方法 利用面向对象方法系统分析产品结构，产品相关数据和产品开发过程的基本属性及３之间的内在联系。结果 建立能够系统描述产品层次结构及其相关档的产品结构类库和系统的体系结构，并在此基础上提出了数据驱动的过程模型和过程管理方法。结论 产品数据模型是ＰＤＭ系统的核心，该模型利用统一的概念对产品结构进行定义，并在此基础上实现产品数据和过程的集成。

Design and Implementing of Data Management in PROMANS

To determine the role of product data model in the product data management and concurrent engineering. Methods Attributes of the product structure, the data related to the product and the product development process and the relationship between them were analyzed by using the object oriented method. Results The classes library of product structure was established. On the basis of the classes library, the data driven process model and process management method was discussed. Conclusion The product data model is the kernel of product data management systems. The model defines the product structure by the unified concept and the product data and process are integrated on the basis of the model.
