面向特征的产品数据库中特征有效性的维护

Maintaining feature validity in feature-oriented product database

并行和协同产品设计已经成为当前的流行设计模式。具有粒度的产品数据库是理想的支持基于网络的协同设计数据源。重点讨论如何维护面向特征的数据库中产品特征模型的有效性。应用所提出的约束解决方法,能保证产品数据库中特征模型的有效性以支持多应用产品协同设计。

Concurrent and collaborative engineering （ CCE } has become an industry trend. A finegrain feature-oriented product database is ideal to support web enabled collaborative engineering services. It＇s describes the maintenance of feature validity in the feature-oriented database on the basis of previous work. Under the proposed constraint solving methods, feature information, which includes feature geometry and constraints, can be well managed and thus collaborative product design among multiple applications can be achieved.
