| 摘 要： | 针对多属性群决策问题,以梯形模糊数为基础,给出了一种群决策方法.该方法采用梯形模糊数表示决策者偏好和决策者权重,由偏好矩阵和权重向量构造出加权决策矩阵,通过期望值计算和归一化处理得到规范化的决策矩阵,采用OWA算子进行集结,结合属性权重得出决策结果.最后通过算例表明了该方法的有效性和实用性.

| Abstract: | In order to solve multi-attribute group decision-making problems,a new method for group decision-making is proposed based on the trapezoidal fuzzy number.According to the method,the preference and the weights of the decision makers are expressed in the form of trapezoidal fuzzy number.Firstly the weighted decision matrices are constructed by using the preference matrices and the weight vector.Then the normalized decision matrices are obtained through the computing of expected evaluation and standardized exp... |
