In this paper, firstly an integrated procurement and logistics service system is designed based on SOA to reduce the cost of the system reengineering. Then, in order to compensate for the lack of analyzing service quality of SOA, the value model is introduced into the SOA based service system to formally describe the customer';s service requirements of both function and non-function aspects. Next the extended UML sequence diagram is applied to describe the service process. Furthermore Pi calculus and the value state graph is employed to verify the realizability of the target value, and the value function to quantitatively measure the value implementation degree is used to check that whether and to what degree the customers'; service requirements is met by procurement logistics system. Finally the simulated data case of a procurement logistics system is made use of to analyze and verify the methods proposed in this paper. The result shows that introducing the value model into the SOA based service system can effectively compensate for the lack of analyzing service quality of the system such as the procurement logistics system, so that the methods presented in this paper can provide reference for designing services architecture and optimizing the combination of the services for the procurement logistics system.
