摘　　要：大型企业各部门可能采用了不同种类的软件产品,需要跨部门集成。然而,产品多样性、网络异构性给PDM与三维CAD的互操作及紧密集成造成了困难。本文提出一种面向服务和跨产品平台的双向集成策略,将PDM与主流三维CAD采用各自的统一服务代理封装成Web服务,采用各自的统一集成代理请求对方服务,以达到双向数据、业务和界面的集成。本文所提出的CAD统一接口模型可构建CAD统一服务代理,屏蔽了不同CAD二次开发接口的差异性;提出了一种GUI和网页元素的统一用户界面模型,能方便CAD交互式图形操作和Web页面操作的互动集成。应用表明,统一代理与Web服务技术相结合可以以较小代价、一致的方法较好地解决PDM与三维CAD的异构集成问题。It is likely that the individual department of a large company deploys various software that need cross depart ment integration. While product diversity and network heterogeneity can result in difficulties in interoperability and tight integration between PDM and 3-D CAD. This paper presents a service-oriented cross-product bidirectional integration strate gy, in which PDM and major 3D CAD are encapsulated as web services by their respective unified service agents, and they request each other for services through their respective unified integration agents for the purpose of bidirectional integration in data, business and user interface. A CAD unified interface model is provided so as to mask the dissimilarities of the API of various 3D CADs and to implement the CAD unified service agent. A unified user interface model for GUI and webpage elements is presented to facilitate interactive integration between the operation of CAD and webpage. The practical application demonstrates that combining unified agents and the Web Services technology can solve the problems of heterogeneous integration between PDM and various 3D CADs at less cost.
