摘　　要：针对决策信息为区间Pythagorean模糊数,属性权重不完全确定的多属性决策问题,提出了一种基于相对熵的AQM决策方法。首先,提出区间Pythagorean模糊数的相对熵,计算了各方案与区间Pythagorean模糊正理想方案和负理想方案间的相对熵,据此构建了基于方案相对满意度最大的非线性规划属性权重确定模型;其次,针对每个属性,利用新的区间Pythagorean模糊数得分函数计算方案的0-1优先关系矩阵,依据AQM方法对所有0-1优先关系矩阵进行融合得到合成0-1优先关系矩阵,并确定了方案的综合度,由此获得方案的排序。最后,以软件开发项目的选取为实例说明了该方法的可行性和有效性。For the problem of multi-attribute decision making,in which the attribute values are the intervalvalued Pythagorean fuzzy numbers and the information about criteria weights is incomplete,a decision making method is proposed based on relative entropy and AQM method. Firstly,the relative entropy of interval-valued Pythagorean fuzzy numbers is defined,the relative entropy between alternative and ideal( critical) alternative is obtained,and an optimization model is established to obtain the criteria weights. Then,the 0-1 precedence relationship matrix for each alternative on each attribute is given by using a new score function,and according to AQM method,the combination 0-1 precedence relationship matrix of alternatives is composed. Furthermore,the comprehensive scale is obtained and a ranking of alternatives can be determined by using the comprehensive scale. Finally,the method is used to select a software development project so as to verify the effectiveness and feasibility.
