摘　　要：针对属性值为一般模糊变量、属性权重信息完全未知但已知方案偏好关系的模糊多属性决策问题,给出了决策方法。首先通过求解一个模糊期望值模型来确定属性的权重,然后基于简单加权平均法则来计算各方案的模糊综合评价值,再根据比较模糊变量大小的期望值方法来对方案进行排序。最后给出一个算例。A method was presented to deal with the fuzzy multiple attribute decision making problem with preference values on alternatives, in which the attribute weights were unknown completely and the attribute values were given in the forms of fuzzy variables. A fuzzy expected value model was constructed to determine the attribute weights. Then, basing on additive weighting average, we computed the fuzzy utility values of various alternative, and ranked alternatives by expected value method of fuzzy variables. Finally, a numerical example is given to illustrate the proposed method.
