Abstract: To solve the problem of automatic service matching and composition under networked logistics environment， an integrated logistics application framework based on semantic Web service was proposed. Functional modules were designed which were generated in service process. Service matching algorithm and process optimization method in service matching and process optimization modules were studied in particular. A matching algorithm was presented based on the formulized definition of semantic description for Web services. By evaluating matching scores of functions， I/O parameters and Quality of Service parameters， the overall matching degree of a candidate service and its service template were calculated. Nonlinear constraint programming model and algorithm were also presented. Validity and efficiency of the model and algorithms were proved in a composite logistics service process.
