The main use of semi-automatic service composition model is a combination of methods , while using convenient service options , and dynamic binding techniques to enhance the flexibility of service composition ; when business processes a Web service exception , BPEL execution engine can UDDI registry center for inquiry, the replacement of abnormal dynamic Web service to prevent interruption of business processes . This service composition model based on a combination of business process services by running analysis, this paper shows that the Web service composition process designed to facilitate reuse of existing services, reduce unnecessary duplication of function code is written , greatly improve the software production efficiency.
