摘要：The Software as a Service (SaaS) model, where software is delivered on-demand and priced on-use, has been made possible by the widespread adoption of fast Internet access, combined with the widespread acceptance of Service oriented architecture (SOA) based solutions. By integrating outsourced software into project development can be challenging or even risky. The trustworthiness of service providers is commonly measured by their reputations. There exist so many web services that share same functional properties(reputations); so it is often a challenging effort to select a credible web service based on their various history Quality of Service (QoS) records. In view of this challenge, a QoS based service selection method is considered based on credibility evaluation associated with negotiable and nonnegotiable QoS dimensions. More specifically, the historical empirical data, i.e., execution price, reputation and success rate of a service, are used for evaluation purpose.
