摘要
在面向服务的应用中,如何从众多满足要求的Web服务中选取一个最能满足客户要求的服务已经成为人们越来越关心的热点话题。提出了一个新的QoS计算模型来为Web服务提供QoS保障,该模型使用基于QoS的方法来搜索最合适的服务和采用基于用户期望值的方法来计算质量属性和服务的QoS。
The ability to discover required Web Services and to select the most proper one is becoming critical in service - oriented applications. To guarantee QoS of web services, a new QoS calculation model is proposed, in which the expectation - based method is used in calculating QoS of quality attributes and services.
