摘要

摘要: 多QoS注册中心并且QoS模型异构给服务选择带来巨大困难。借鉴多属性群决策(MAGDM)理论的基本思想，该文提出一种解决上述难题的多注册中心和模型异构的Web服务选择算法(MRHQ_WSSA)。MRHQ_ WSSA算法能综合评估各QoS注册中心的QoS信息，从而获得QoS综合最优的服务组合计划。MRHQ_WSSA算法包括5个步骤：用户偏好规格化、群偏好确定、加权规格化决策矩阵、确定群理想方案、计算群贴近度。最后通过实验验证算法的优势和有效性。

Abstract: Web service selection based on QoS is still challenging because the multiple QoS registration centers and heterogeneous QoS models make decision-making hard. Based on Multi-Attribute Group Decision-Making (MAGDM) theory, this paper presents a novel Multiple Registration centers and Heterogeneous QoS models Web Service Selection Algorithm (MRHQ_WSSA) to solve the above difficulties for the first time. Through evaluating the QoS information of all QoS registration centers, MRHQ_WSSA can obtain the synthetically optimal composition plan. It includes five main steps: normalizing the users QoS preference, calculating the group preference, weighting normalized decision-matrix, determining group ideal solution and calculating the relative closeness to the group ideal solution. And a set of experiments demonstrate the benefits and effectiveness of the approach.
