摘　　要：质量评价在Web服务生命周期的服务选择、实时监控、管理和计费等阶段占有越来越重要的地位,且模糊理论已应用于该领域。文章从区分冗余隶属度的角度对模糊综合评判算法进行改进,以消除指标隶属度中对目标分类不起作用的冗余数值,在没有冗余数据的条件下实现隶属度转换,并应用于Web服务QoS的评价。Quality evaluation has become more and more important in Web Service life cycle on Service Selection, real-timemonitoring, management, accounting and other stages. And fuzzy theory has been applied to the field. In this paper, the algorithm of fuzzy comprehensive evaluation is ameliorated on differentiating redundancy membership degrees. It eliminates redundant data in membership degrees of index which are useless for objective classification. Then it realizes the conversion of membership degrees without redundant data. It can be used in the evaluation on the QoS of Web Service.
