Service-Oriented Architecture (SOA) provides a flexible framework for service composition. In a service market scenario, given a functional description of service, different providers may offer diverse service implementations that match such a functional description, but differ for some QoS attributes. It is increasingly vital to provide a service selection and recommendation mechanisms that best meet the QoS requirements of the service user. Different from most of the existing approaches to service selection, we consider a Web service selection and ranking mechanism with multi-QoS attributes, focusing on simulating degree of consumer satisfaction and hypothesizing consumer preference historical information. Efficient service selection mechanism and heuristic algorithm for consumer preference of multi-QoS are presented in this article and their performances are studied by simulations.
