摘　　要：随着跨组织业务的拓展,分布式工作流已经成为研究热点。通过对分布式工作流和P2P技术的分析,提出了一种基于P2P的分布式工作流平台。描述了它的网络架构和系统架构,建立了底层的消息通信机制,给出了工作流的定义和执行的分布式设计。相对于传统的工作流平台而言,该平台具有可靠性高、异步协同能力强和应用广泛的特点。With the extension of across organization business, the distributed workflow becomes a research focus. Based on analysis of the technologies of distributed workflow and P2P, a BPDW （distributed workflow platform based on P2P） is presented. Its network frame and applied architecture were built, the basal communication mechanism based on messages was established. The design of dis- tributed definition and implement of workflow based on this model was put forward. Compared with traditional workflow style, this platform is characterized by more high reliability, ability of asynchronous collaboration and extensive annlication.
