摘　　要：对区间直觉模糊信息的集成方法进行了研究.定义了区间直觉模糊数的一些运算法则,并基于这些运算法则,给出区间直觉模糊数的加权算术和加权几何集成算子.定义了区间直觉模糊数的得分函数和精确函数,进而给出了区间直觉模糊数的一种简单的排序方法.最后提供了一种基于区间直觉模糊信息的决策途径,并进行了实例分析.Methods for aggregating interval-valued intuitionistic fuzzy information are investigated.Some operational laws of intervalvalued intuitionistic fuzzy numbers are defined.Based on these operational laws,some aggregation operators,including interval-valued intuitionistic fuzzy weighted arithmetic aggregation operator and interval-valued intuitionistic fuzzy weighted geometric aggregation operator,are proposed.The score function and accuracy function of interval-valued intuitionistic fuzzy number are defined,and based on these two functions,a method for ranking interval-valued intuitionistic fuzzy numbers is presented.Finally,an approach for decision making with interval-valued intuitionistic fuzzy information is developed,and a practical example is provided to illustrate the developed approach.
