摘要:
群体活动在日常生活中非常广泛,面向群体的信息服务提供是必需解决的问题.群体规模较大和混合数据类型QoS模型给Web服务选择带来巨大困难.基于混合QoS模型,借鉴多属性群决策理论,提出面向大群体用户的服务选择算法.包括5个步骤:群体偏好确定、族加权权重确定、构造族加权规格化决策矩阵、确定理想方案、计算贴进度.另外,还介绍了一种Web服务QoS模型,能够描述实数、区间数、直觉模糊数表示的QoS信息.实验数据表明,该算法能够很好地解决混合QoS模型的大规模群体用户的服务选择问题
Abstract:
Group activities in the daily lives are very popular,so the information service provider for group is required to be solved. It is difficult for Web service selection to be larger group scale and hybrid QoS model. Based on hybrid QoS model and learned from multi-attribute decision theory,big group-oriented Web service selection algorithm is presented. It includes five main steps:determining group preference,calculating weighted cluster weights,constructing cluster weighted normalized decision-making matrix,determining the posi-tive-ideal and negative-ideal solution,calculating close-degree. Other contribution is a Web service QoS model to describe QoS informa-tion with real numbers,interval numbers and intuitionistic fuzzy numbers. Experimental results show that the proposed algorithm can solve the problem of hybrid QoS-aware big group-oriented Web service selection very well
