摘　　要：研究了属性权重信息完全未知且属性值以三角模糊数形式给出的不确定型多属性决策问题.利用模糊数数据的变异系数来度量三角模糊属性值之间的差异程度,给出了求解属性权重的简洁公式和一种基于可能度的决策方案排序方法.This paper studies a kind of uncertain multi-attribute decision-making problems, in which the information about the attribute weights unknown are completely and the attribute values are in the forms of triangular fuzzy numbers. The deviation degrees between the triangular fuzzy attribute values are measured by applying dispersion coefficient of fuzzy-valued data, a simple formula for obtaining the attribute weights is given, and a priority method based on possibility degree for the uncertain multi-attribute decision-making problem is also proposed.

关 键 词：多属性决策 变异系数 可能度 排序方法
