QoS driven selection approaches for Web Services Composition are used to choose the best solution among candidate services which have the same functions. This paper focuses on the Web services composition problem, and introduces the multi-dimension QoS model. Based on the QoS model, the QoS-driven web service selection model was proposed and described in details. According to these models, service composition problem can be considered as single-objective multi-constraints optimization problem. A brief discussion of approaches to solve the optimization problem is given.
