摘　　要：给出了一种基于有色Petri网的网格服务工作流模型——有色服务流程网(ColoredServiceFlowNet),在此基础之上分析并提出服务流水线(ServicePipelining)的概念.该模型将图像数据传输作为服务运行的触发条件,提高了服务流程处理的效率,减少了用户作业的执行时间.In this case, it becomes a great challenge to provide efficient and convenient tools for image data transmission and Grid Service composition. A grid workflow model based on colored Petri net for grid service, colored service flow net （CSFN）, was established, in which the image date transmission was taken as requirements for the service flow to improve the efficiency of settling service flow and reduce the time of executing users＇ tasks. The conception of service pipelining was also suggested.
