协同设计网格及其关键技术

The Collaborative Design Grid and Its Key Techniques

针对协同设计中的资源共享和协同工作问题,通过分析产品设计和仿真过程对协同设计网格的功能需求提出了协同设计网格的概念.基于网格中间件建立了协同设计网格的4层体系结构,利用G lobus工具集实现了协同设计网格服务,并基于W eb开发协同设计网格的门户来封装网格服务.该技术为分布在异地的设计人员提供了高级的网格服务和友好的图形化界面,从而最大程度地实现资源共享和协同工作,为远程协同设计的实施提供了新思路和新方法.

For the problems of resource sharing and collaborative work in collaborative design ,the functional requirement of collaborative design grid （CDG） was analyzed during the product design and simulation process. The concept of CDG was put forward, and its corresponding four-tier architecture was set up based on the grid middleware. The grid services in the CDG were realized by means of Globus toolkit. The grid portal of the CDG based on web was developed to encapsulate the grid services. This technology provides advanced grid services and friendly graphical interfaces for dispersed designers, and then will furthest realize resource sharing and cooperative work. At the same time new idea and new method are provided for implementing remote collaborative design.
