提出了确定区间数互反判断矩阵权重的新方法.首先,给出了能够反映决策者风险偏好的区间数表示形式.接着,刻画了区间数互反判断矩阵的一致性检验方法.对不一致的区间数互反判断矩阵,通过求解优化模型及一致性定义提出了区间数互反判断矩阵的一致性逼近方法.基于一致性区间数互反判断矩阵,给出了满足决策者不同风险偏好的权重计算公式.最后,通过两个例子说明了所提出方法的有效性.
This paper proposes a new approach to determine the weights of interval reciprocal judgment matrices.Firstly,the expression of interval number that can reflect decision-makers risk preferences is introduced.Then,a consistency checking approach of interval reciprocal judgment matrices is given.For inconsistent interval reciprocal judgment matrices,a consistency approximation approach of interval reciprocal judgment matrices is developed by solving an optimal model and using the consistency definition.Furthe...
