摘　　要：开放网格体系结构OGSA规范通过整合网格和Web服务技术确定了网格服务分布式系统框架,但其中关于网格服务合成的方面并没有定义相应的规范,业务流程执行语言BPEL4WS是应用于Web服务上的服务合成规范。通过分析网格服务和Web服务的异同,设计出一种可行的模型,解决了BPEL4WS不支持网格服务中部分特性的问题,从而可以将BPEL4WS应用于网格服务合成上。The open grid services architecture specifications establish a distributed grid services system framework by integrating the grid and web services technologies, but these specifications have no definition about grid services composition. The business process execution language for web services is applied to the web services composition, The difference and similarity about grid services and web services were analyzed, then a kind ofmode was designed, which could resolve the problem that BPEL4WS doesn＇t support some grid services＇ characteristics, so that BPEL4WS can be applied to grid service composition.
