摘要 基于QoS的Web服务选择能为用户提供更好的服务质量,而基于用户对QoS的需求和偏好的模糊性来进行Web服务选择是其中的一种方法。针对如何通过这种方法合理地获得最优候选服务集,是Web服务架构待解决的一个问题,提出了一种支持QoS和用户需求的Web服务选择模糊算法。该算法将用户对QoS的需求及偏好的语言描述进行去模糊化,然后选择出最符合用户需求的服务集。通过对模拟的服务质量数据进行实验,验证了该算法的优越性和有效性。 QoS-based Web service selection can provide better service quality.There was one method to select Web service which utilized fuzziness of user's needs and preferences for QoS.It was an urgent problem to obtain most excellent candidate service set reasonably.This paper proposed a Web service selection fuzzy algorithm for QoS and user's requirements.This algorithm defuzzified user's language description of the needs and requirements for QoS.Besides,it selected the most reasonable service set.This paper studied simulative service quality data and verified the advantage and availability of this algorithm.
