摘　　要：动态服务组合是构建面向服务、松耦合、集成化的应用系统的主要途径。现行的动态服务组合方法中,工业界倾向于采用BPEL建模服务流程,而语义网研究团体则吸取AI规划的思想以实现Web服务组合,以上两种方法都不同程度地存在各自的不足。在对上述方法进行对比分析的基础上,提出了一种结合AI规划和工作流技术的动态服务组合方法。实践表明,这种方法能有效克服采用单个方法所造成的不足,并可实现从需求到部署的全过程。Dynamic service composition is a major route to build a service-oriented,loose coupling and integrated application system. And by now, the business world has adopted a approach in which Web service instances are composed into flows with a language like BPEL. Academia has propounded the AI approach. These approaches by themselves are piecemeal, and insufficient. Based on the contrastive analysis on these approaches, this paper proposed a dynamic Web service composition method which is integrated the AI planning with the workflow technique. The practice shows that it is an effective method to overcome the single method＇s insufficient and finally achieve the whole process from the requirement to the deployment.
