摘　　要：对属性权重信息不完全、属性值和决策者对方案的偏好信息均以直觉模糊数表示的多属性决策问题提出一种决策方法。首先根据决策者对方案的偏好信息建立多目标规划模型,求出属性权重,接着利用觉模糊加权算术平均算子求出方案的综合属性值,由直觉模糊数的得分函数和精确函数确定方案的排序,最后通过实例证明了该方法的实用性和有效性。A method is presented to deal with the fuzzy multiple attribute decision making problem with preference values on alternatives,in which the information about attribute weights is incomplete,the attribute values and the preference information on alternatives are given in the form of intuitionistic fuzzy numbers.According to the preference information on alternatives given by decision makers,multi-objective programming model is constructed to obtain the attribute weights.Then,intuitionistic fuzzy weighted arithmetic averaging operator is used to aggregate the intuitionistic fuzzy information corresponding to each ahernative,and the alternatives are ranked by the score function.Finally,an illustrative example is given to demonstrate the practicality and effectiveness of the proposed method.
