Abstract: Dynamic service composition is a major route to build a service-oriented, loose coupling and integrated applicanon system And by now, the business world has adopted a approach in which Web service instances are composed into flows with a language like BPEI.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.
