Abstract In order to solve the bottleneck problems of sharing, transferring and reusing of enterprise knowledge resources, caused by the diversity of knowledge carriers and the heterogeneity of information for describing knowledge resources, a metadata model of process planning knowledge resource network (PPKRN) was presented. The formal definition of the PPKRN was introduced through analyzing the current situation of process planning knowledge resources of the enterprises. The model can represent knowledge in a unified standard way by the metadata technology, which is helpful to improve the ordering process of the PPKRN and build the dynamic correlation among knowledge resources effectively. A case on the development of a prototype system used in a Chinese engine enterprise was given to further illustrate the feasibility and validity of the model．

工艺设计知识资源网络的元数据模型研究
由于知识载体形式的多样性和描述知识资源信息的异构性，不利于企业知识资源的共享、转移和利用,通过对企业工艺设计知识资源的现状分析,给出工艺设计知识网络的形式化定义,利用元数据技术,提出工艺设计知识资源网络(PPKRN)的元数据模型.该模型有助于实现企业知识资源的统一、透明、规范表示,促进工艺设计知识资源网络的有序化,并能够有效的构建知识之间的动态关联性.以国内某汽车发动机制造企业开发的工艺设计知识资源网络原型系统为例,进一步说明了所提出模型的可行性和有效性.
