网格工作流中协同机制的研究与实现

Study and Implementation of Cooperation Mechanism in Grid Workflow

对计算机支持的协同工作(CSCW)和工作流进行了深入探讨.在分析网格工作流特点的基础上,提出了网格协同工作流参考模型,并详细分析了基于协同上下文概念的网格协同工作流的协同机制及其实现方法.最后,给出了此协同机制在银行贷款系统中的应用实例.

This paper presents a profound study of the Computer Supported Cooperative Work （CSCW） and workflow system. Based on the former researches, the paper presents a more useful grid workflow system reference model with a consideration of the properties of grid environment. An analysis is made of the cooperative mechanism based on cooperation context of Grid workflow system and technologies about message middleware. The implementation method of the cooperation mechanism for grid workflow is proposed, and then an application instance is provided to illustrate our approach.
