摘　　要：对区间直觉纯语言信息的集结方法进行了研究.定义了区间直觉纯语言集及其运算法则和区间直觉纯语言变量的得分函数和精确函数,给出了一种简单的区间直觉纯语言变量的排序方法.进一步,提出了一些基于区间直觉纯语言信息及其运算法则的信息集结算子.在此基础上,给出了一种专家权重、属性权重及属性值均以语言标度形式给出的区间直觉纯语言信息集结方法,并将此方法应用到多属性群决策中.最后通过实例分析表明了该方法的有效性和可行性.Methods for aggregating interval-valued intuitionistic pure linguistic information are investi- gated. Interval-valued intuitionistic pure linguistic set, as well as its operational laws, the score function and accuracy function are defined. Based on the two functions, a method for ranking interval-valued in- tuitionistic pure linguistic variables is presented. And then, some new interval-valued intuitionistic pure linguistic aggregation operators based on the interval-valued intuitionistic pure linguistic evaluation scale and the operational laws are developed. Moreover, methods for aggregating interval-valued intuitionistic pure linguistic information, in which all expert weights, attribute weights, attribute values take the form of linguistic labels are proposed. Also, the methods are applied to the multiple attribute group decision making. And finally, the feasibility and effectiveness of the methods are shown by an illustrative example.
