基于知识的产品设计数据库的设计与实现

基于知识的新一代产品设计数据库－－设计知识库是一个用来并行、方便地描述、获取、共享和再利用设计知识的、智能化的、基于知识的设计制品模型系统，这些存放在设计知识库的知识能够使产品全生命周期中各阶段的知识表示、获取、分享以及再利用成为可能，设计知识库的研究致力于开发支持基于知识的设计／制造过程的信息建模框架。利用SHARED面向对象模型对设计制品信息进行了建模，并且研究了以何种格式、何种规范来存储设计制品的信息以满足设计制品知识库对制品建模的要求，最后，对设计知识库原型系统的实现技术进行了讨论。

Knowledge-based New Generation Product Design Databases

Knowledge-based new generation product design databases--design repositories are a intelligent and knowledge-based design artifact model system used to describe,capture,share,reuse design knowledge concurrently,and the knowledge stored in design repositories makes it possible that the knowledge in different stages in the life cycle of the product can be represented,captured,shared and reused.The research of design repositories attaches importance to the development of the information modeling framework that supports knowledge-based designing/manufacturing process.This article uses SHARED object-oriented modeling to model the design artifact information,and studies what form and what specification are adopted to store the design artifact information in order to satisfy the artifact modeling requirement of design repositories.Finally,the implementation technology of prototype design repositories is discussed.
