可重用集成设计单元模型研究

Research on Modeling of Reusing Integrated Design Unit

设计重用技术的核心是可重用对象的建模问题。该文提出可重用集成设计单元,用它来表达、组织和管理可重用的信息。首先给出了可重用集成设计单元的定义,分析了它的特点;然后建立了可重用集成设计单元的信息模型;随后讨论了可重用集成设计单元的建模技术———面向对象技术及元数据(Meta-data)管理技术。接着提出了两种建立可重用集成设计单元的方法:有目的地建立可重用集成设计单元和从已有资源中挖掘提取可重用集成设计单元。最后,阐述了在PDM系统上通过出版/订阅(Publish/Subscribe)方式建立可重用集成设计单元库的具体实现方法。

Core issue of design reuse technology is modeling of reusing object.The paper brings forward integrated design unit which expresses and organizes and manages reusing information.First,the paper sets the definition of reusing integrated design unit and analyze s its characteristic.Later,it discusses modeling technology of reusing integrated design unit-object -oriented technology and Meta -data management technology.Following,it puts forward two methods of establishing reusing integrated design unit:purposefully establishing method and establishing method mining from enterprise design resource.Finally,material implementation method of database of reusing integrated design unit via Publish/Subscribe pattern based on PDM system is expounded.
