中文摘要: 面对多个功能相同或相似的服务, 服务的QoS是服务选择中重要的考虑因素. 将QoS属性分为精确数型、区间数型和三角模糊数型. 在此基础上, 利用TOPSIS(technique for order preference by similarity to an ideal solution)条件下的多属性群决策模型给出了服务选择过程, 该过程考虑了多个决策者在决策过程中所占的权重, 以及多个决策者不同的QoS偏好权重. 通过一个实例验证了该方法的有效性.
Abstract:When facing with multiple Web services with the same or similar functionality, QoS (quality of service) has become an important criterion for users to select the appropriate Web services. We present a QoS model, the QoS attributes are divided into exact numeric type, interval numeric and Triangular fuzzy numeric. We propose a kind of multi-attribute group decision-making model based on TOPSIS (echnique for order preference by similarity to an ideal solution) to select Web services, which considers weights of multiple decision makers and weights of the QoS preference in the decision process. The example proves that the method is feasible.
