摘　　要：动态服务组合为跨组织业务流程的快速开发提供了重要技术支撑。传统的集中规划的组合方式不能很好适应开放环境所提要求。提出一种基于分布式层次任务网络的服务组合策略,分析了实现该策略的组件的结构和功能,并定义组件间的Web服务接口,给出该策略下跨组织流程的开发方式,并以应用实例说明该策略对开放组织之间业务流程开发的有效支持。Dynamic web service composition has proved to facilitate the rapid development of cross-organizational business processes. But the traditional centralized planning is incompetent under the open environment. A distributed hierarchical task network based on service composition strategy is proposed. The structure and function of the components that carry out the strategy are discussed. The service interface among components is defmed. The procedure is also provided to develop cross-organizational processes using the strategy. A case study is given to demonstrate how it works.
