摘要
建立在产品数据管理系统基础上的工程变更管理是指管理处于预发布和发布生命周期状态的产品数据。本文在Windchill的基础上建立了面向对象的工程变更管理模型,实现了基于产品数据之间关联关系的配套更改检查,提出了变更对象间的同步机制,并给出了在某大型制造企业的应用实例。
Engineering change management, which is basis on Product Data Management (PDM) system, controls the pre-released and released product data. In this paper, an Object Oriented model of engineering change management on the basis of windchill has been established. Moreover, the integrity check based on the relationship among product data is discussed, and the synchronicity among EC objects is put forward. Finally, an implementation of the model in a manufacturing company is given as an example.
