网络协同环境下产品设计知识的表达体系研究

摘要

This paper proposes a collaborative environment that is suitable for the implementation of product design knowledge sharing knowledge classification system and the knowledge representation model on the basis of the anal-ysis of product design knowledge management features in the networked collaborative environment. According to the characteristics of networked collaborative environment knowledge sharing,product design knowledge could be di-vided into six types,such as knowledge of characteristic parameters ,the knowledge structure of products,principle knowledge,exemplary knowledge,design normative knowledge,experiential knowledge. Based on the design of knowledge expression system ,shared knowledge can be divided into data table,the language data,graphics,draw-ings,template class five kinds of expression,and USES the hierarchical XML description language,all kinds of knowledge and the expression of the template.%在分析了网络化协同环境下产品设计知识管理特性的基础上，提出了一种适合于实现协同环境下产品设计知识共享的知识分类体系和知识表达模型。根据网络化协同环境下知识共享的特点，将产品设计知识进行了分类。按照设计知识的表达体系将共享知识分为数据表类、语言数据类、图形类、图纸类、模板类五种表达方式，并采用分层的 XML 描述语言，给出各类知识的表达模板。
