摘要 研究偏好信息为三角模糊数互补判断矩阵形式给出的方案排序方法.根据三角模糊数互补判断矩阵完全一致性的概念,建立了一个基于最小方差的非线性规划模型.通过求解该模型,得到三角模糊数互补判断矩阵的权重向量,并利用三角模糊数排序公式对决策方案进行排序.最后通过算例分析表明了所提出的方法是可行而有效的. The priority mothod of complementary judgment matrix is studied, in which the preference information takes the form of triangular fuzzy number judgment matrix. Based on the concept of complete consistency for triangular fuzzy number complementary judgment matrix, a non-linear programming model is set up based on least variance method. The weight vector of triangular fuzzy number complementary judgment matrix is obtained by solving the model. By using a priority formula of triangular fuzzy numbers, the decision alternatives are ranked. Finally, a numerical example shows the effectiveness of the method.
