Service-selecting approach based on domain-specified 'Quality of Service' model and its application in logistics

With the rapid growth of modern service economics and the popular adoption of web services, more and more service industries are beginning to deliver services with web service technology. One of the key issues is how the service consumer should search for services within the plentiful service repositories, and especially select a suitable and optimal service from candidates with similar features. However, most of the researches on service selection focus on the general criteria of web service, but ignore the domain-specified needs. This paper proposes a domain-specified quality of service model and an analytic hierarchy process-based service-selecting approach by integrating hierarchical clustering algorithms and fuzzy comprehensive evaluation methods. An application in logistics is given to validate the effectiveness of this approach.
