摘　　要：模糊互补判断矩阵是决策者通过指标的两两比较给出的一种模糊偏好形式。根据带有梯形模糊数的互补判断矩阵确定各指标的权重,通过算例说明了该方法的有效性和实用性。Complementary judgement matrix is a kind of fuzzy preference information form given by decisions makers through pairwise comparison on indices. This paper determines the weight coefficient of each index according to the complementary judgement matrix with trapezium fuzzy numbers. Finally, on the basis of a numerical example, it illustrates the method is effective and practical.

关 键 词：梯形模糊数 模糊偏好 互补判断矩阵 期望 权重
