摘要: In a composite service for multiple users, network position of users are different, leading to perceptions one different. addition, parameter values, which vary due many reasons (such as congestions), influence QoS Web services. We propose reliable composition method uses candidate services process requests variety users. Initially, execution paths each kind user calculated. runtime, the optimal chosen according current state. present an application scenarios method.
