摘要： 为了实现协同产品开发中的知识共享，在开放式标准的基础上，提出了一种基于特征模型和网络(Web)服务的工程知识库共享机制.以各类工程数据库、专家知识等作为底层资源而建立工程知识库，并将知识库中的知识对外包装成标准的Web服务；同时，提出了基于异构计算机辅助（CAX）系统特征的产品模型数据转换方法，并将其转换为可扩展标记语言（XML）表述而作为平台无关的信息集成方式；将产品模型的XML表述作为输入，利用Web服务的发布、发现与共享机制来选用合适的Web服务而获取相关的领域知识，以对产品模型进行评估与优化.结果表明，所得数据可以在产品模型和Web服务之间进行交互与转换，可实现高效的知识共享.

Abstract: To achieve knowledgesharing in collaborative product development, based upon open standards, a mechanism to implement the feature and Web servicebased sharing of engineering knowledgebase is proposed. In this mechanism, engineering database or expert knowledge acts as basic resources to construct engineering knowledgebase by the rulebased method, then the knowledgebase is wrapped and exposed to outside by Web services. Meanwhile, a method for part model transforming among heterogeneous Computer Aided X (CAX) systems is presented, which is the featurebased approach by which part models are transformed into platformindependent eXtensible Markup Language (XML) representations. Afterwards, based upon the publishing, finding and sharing approach of Web service, customers can search and choose appropriate Web services and send the XML representations of part models as inputs to gain relevant knowledge to evaluate part models, realizing efficient knowledgesharing.
