英文摘要	A Composite web service's response-time is composed by the response-time of its member web services. In order to make a composite web service meet its user's response-time requirement, the instance of each member web service should be properly selected and bound. In the literature, every member web service is treated in the same way in the composite web service's response-time optimization and its different weight on the effect of user's satisfaction is not considered. However, in a certain scenario, some member services are more sensitive on response-time than others, that is to say, in a given composite web service, when these sensitive services delayed, the decline of users' satisfaction is remarkably greater than other services delayed. In this article, a user perceived response-time optimization method is proposed to reduce the delaying risk of the time sensitive web services, and thus to improve the user's satisfaction of a composite web service. Our experiments validated the efficiency of the proposed method.; EI; 0
