摘要 通过在Web服务动态组合中引入形式化的服务质量(QoS)描述、服务提供商因子、服务消费者因子,提出基于层次分析法的QoS计算方法。该方法根据服务消费者期望值选择QoS因子,利用QoS权重值计算Web服务的质量,在此基础上给出一个基于QoS计算的Web服务组合模型,并通过实例计算,证明利用该QoS计算方法可以得到更高质量的增值服务。 By introducing formal Quality of Service(QoS) description, service provider factor, service consumer factor in Web services dynamic composition, a method of QoS computing based on Analytic Hierarchy Process(AHP) is proposed. It selects QoS factors according to service consumer expectations, computes the quality of Web service with QoS weight, and proposes a QoS-based Web services dynamic composition model. An example is provided to prove that higher quality value-added services can be obtained with the computing method proposed.
