产品模型的演变

The Development of Product Model

在对早期的产品几何模型,当前的产品特征模型进行简要介绍的基础上,对产品模型的发展趋势——PDM环境下面向对象的集成产品信息模型进行了较详细的讨论.PDM环境下面向对象的集成产品信息模型利用PDM提供的产品结构树有效地,直观地表达所有与产品相关的信息以及产品和零部件之间的层次关系,从而建立产品模型,并提供对象管理机制实现产品数据的管理,使得产品信息在结构化的基础上得以充分集成,从而实现产品信息的共享以及一致性维护,避免信息的冗余.

Based on briefly introducing the early geometry model and current feature model of product, wehave detailed discussed the development tendency of product model——the object-oriented integrated productinformation model based on PDM environment which expresses efficiently and directly all related information of product as well as the hierarchy relation between product and its components to establish product model through product structure tree offered by PDM, and offers object management mechanism to realize the man-agement of product data, it make product information integrated fully on the foundation and avoided the infor-mation redundancy in this paper.
