Focusing on the characteristics of supply chain management system, aiming at the integration requirement of Web services in cross-organizational process, this paper brings forward an improved modeling method supporting integration of external Web services suitable forsupply chain management system-Web Service-based Process Model(WSBPM), and extends the ability of the model, I.e. The ability to controlthe execution of services, the ability to sense the external environment and the ability to dynamically select and integrate services. The architecture of supply chain management prototype system based on WSBPM model is presented. The model can efficiently support integration of external Web services in cross-organizational process, which is suitable for software development of supply chain management system.%根据供应链管理系统的特点,以及跨企业过程中服务的集成需求,提出一种支持外部服务集成的建模方法——基于Web服务的过程模型.该模型适合供应链管理系统,扩展了模型的服务控制、服务感知和服务选取功能.给出系统体系结构,构建一个基于Web服务过程模型的供应链管理原型系统,该模型能有效支持跨企业过程中的外部Web服务集成,可用于供应链管理系统的软件开发.
