摘　　要：对基于几何距离和混合平均算子的群决策一致性问题进行研究。定义两个直觉模糊数的几何距离和相似度以及群决策下基于混合平均算子的直觉判断矩阵之间的集成方法;给出群决策下判断矩阵之间的相似度计算公式;归纳群决策一致性分析的步骤;最后通过例子对该方法进行说明和分析。The problem of consistency analysis in group decision making based on geometrical distance and IFHA is studied. First the geometrical distance and the similarity degree of two intuitionistic fuzzy numbers were defined, the aggregation operator of intuitionistic judgment matrices based on IFHA is given, and the formula of the similarity between intuitionistie judgment matrices is given, then the steps of consistency analysis in group decision making are generalized. Finally a case is given to illustrate and analyze the approach.
