摘要
在介绍描述产品信息的扩展赋权有向图之后，研究了产品数据模型在设计与制造过程不同阶段的变化。提出了在统一数据模型的基础上，以工艺设计为纽带，实现 PDM/CAPP/MRPⅡ系统集成的方法。最后给出了应用实例。
After the extended directed graph with weightings for describing product information is introduced,the changes of product data model during different stages of design and manufacturing are studied. The integration method for PDM/CAPP/MRPⅡ is proposed on the basis of an unified data model.Process design serves as the linkage in the integration.A case study is given as well.
