Composite service selection model based on two-dimensional variable weight

Abstract

With the development of computer technology and cloud computing, service trade has been widely used and more and more composite services with enhanced features and functionality are provided. The composite services are selected based on service selection model. At present studies on the selection model of composite services only consider the quality of service, but ignore the user's selection intention. So how to select a composite service to better satisfy the user's need has become a new challenge. A new composite service selection model is proposed in this paper, based on two-dimensional variable weight method. This model considers not only the quality of service features, but also service execution information and user's intention. In this way the composite service which can better meet user's demand can be selected.
