A Grid Based Collaborative Design System

摘要

A collaborative design system architecture based on Grid is proposed. The architecture can take full advantage of grid features such as computing capability, massive data storage and device sharing etc., which is more suitable for the development of a complex collaborative design environment compared with the widely used Distributed Component Object and existing Grid based collaborative design architectures. Under this architecture, the construction method of Grid services is researched. Parallel and distributed Grid computing technology is used to increase the efficiency of complex product design. A collaborative modeling method based on XML is put forward to support real-time modeling by using design semantics instead of 3D solid model data transport. Finally, a collaborative design prototype system based on Globus Toolkit 4.0 is presented and analyzed.
