针对传统流程模式在互联网应用的局限性,为提高Web服务发现组合能力,提出了社区云的概念,用社区云组织管理Web服务,可以屏蔽服务多样性和多变性带来的复杂性.研究了服务的抽取和社区云服务池的构建方法以及相应的组织和管理机制.在此基础上,构建了一种适用于个性化按需流程生成的云计算支撑平台框架,给出了各个部分的作用及相互间的关系.通过该平台自动生成个性化按需流程,并验证了流程的正确性.%To solve the limitation of traditional process application on Intemet and improve the capability of web services discovery and combination, community cloud is proposed. Community cloud is used to manage web services. It can shield the complexity by the variety and variability ofweb services. Then extraction ofservices, construction ofcommunity cloud pool and its organization and management mechanisms are studied. In this basis, a cloud computing framework platform generating customized process is designed, and each models' function and relationship are described. Based on these, this platform can generate customized process automatically and verify the correctness of the customized process.
