基于共享工作空间的协同系统关键技术的研究

The Research of Collaborative Graphics Editing System(CGES) Based on Place

协同设计是当前计算机支持下的协同工作(CSCW)研究领域的前沿课题之一,文章针对构建协同CAD设计应用环境,提出了一种基于共享工作空间的多任务、多角色协作模型(PBCEs),建立了相应的访问控制和并发控制机制,并在一协同设计系统CoopCAD系统中得到了运用,较好地满足协作应用系统的要求。

Cooperative Design is one of the front areas in Computer-Supported Cooperative Work （CSCW）.Based on the analysis of the structure of multi-task,a cooperative model of multiplex tasks and roles for place-based CSCW application is introduced in this paper to design Cooperative CAD application environment,the mechanism of accessing cortrol and concurrent control is found and implemented in a cooperative design system CoopCAD.Finally it is proved to satisfy the requirement of Cooperative Design System.
