With the development of theory and technology of web service, Web Service Composition has become the core Service-Oriented Computing technology. It is important for business process to select the best service components with multi-dimensional QoS assurance to construct a complex one. In this paper we propose a web service composition model with multiple QoS constraints. We define the utility function as the evaluation standard considering all QoS parameters of each service component and use Subjective-objective Weight Mode to set the weight of each QoS metric.
