摘　　要：给出属性值为直觉模糊数,属性权重完全未知但已知方案偏好关系的模糊多属性决策问题的决策方法。通过建立一个模糊期望值的线性规划模型来确定属性的权重,基于简单加权法则来计算方案综合期望值。利用比较期望值大小的方法对方案进行排序。最后通过实例说明了该方法的可行性和有效性。A method was presented to deal with the multiple - attribute decision - making problem with the preference values on alternatives, in which the attribute weights were completely unkonwn and the attribute values were given in the form of intuitionistic fuzzynumbers. A fuzzy expected value goal programing model was constructed to determine the attribute weights. Then, the utility values of alternatives were obtained based on additive weighting average land ranking alternatives were derived by using the expected value method Of ranking fuzzy variables. Finally, a numerical example was to illustrate the feasibility and effectiveness of the method.
