PLM中产品数据的建模及其过程状态的管理

采用面向对象的思想，论述了 PLM 中基于零部件的产品数据的组织形式，包括
产品模型、定型产品。在此基础上，提出了基于时间点衡量产品数据过程状态的方法，结合工程变更来管理过程状态的改变，为企业实现产品数据的全生命周期管理以利于信息的集成提供了新的思路。

Abstract: An organization model of the product data based on the part in product lifecycle
management with the Object-Oriented method,including product model and case-hardened
product was discussed.Based on what was mentioned above scaling the process-status of product data with time and the management about process-status changing of product data with engineering change were put forward,Which provided a new idea for the enterprise to realize the product data management in all lifecycle and to facilitate information integration.
Key words: product lifecycle;modeling;process status;engineering change
