This paper first presents a virtual community service architecture based on the Open Grid Service Architecture (OGSA). A stochastic high-level Petri net model is given to realize the Quality of Service (QoS) based scheduling of community service resoures.

• 针对这些问题提出了基于开放网格服务结构(OGSA)的虚拟社区服务网格体系结构；并给出随机高级Petri网模型；以实现一个基于服务质量(QoS)的社区服务资源调度.
