摘　　要：为了适应图形计算机辅助设计系统的异地广域协同任务要求,分析了Web服务概念体系在图形计算机辅助设计网络化协同集成应用中的作用,构架了一种以Web 服务为基础的图形计算机辅助设计协同设计框架模型,并由此给出了一种基于优先权控制的分层式协同设计过程模型,提出了一种集中式的冲突解决方法。最后,通过应用实例验证了模型的有效性。该模型基于Internet构件,能够适应协同设计者分布广域性的特点,同时又能提高设计任务的精确性和设计效率。In order to satisfy demands of the designers in different areas and to facilitate the collaborative graphics in Computer Aided Design(CAD) systems, the concept of Web services was introduced and its function for implementing integration of the Internet collaborative graphics CAD systems was analyzed. A model of collaborative design framework of graphics CAD systems using Web services was presented, and a layered collaborative design process model based on priority-controlled method was put forward for the framework, then a centralized-controlled conflict resolving method was proposed. The validity of the collaborative design model was confirmed by citing some successful cases, which had already been put into practice. The structure of the model is founded on Internet and adapts to the features of collaborative task designers who are geography decentralized. In the same time, it improves accuracy of the collaborative task and CAD systems' productivity.
