Abstract: In this paper, the operation laws of the intuitionistic fuzzy uncertain linguistic variable is discussed, and the intuitionistic fuzzy uncertain linguistic weighted geometric operator is obtained, based on the nullnorm and conjugate nullnorm operator. Further, a method of multiple attribute group decision making using an aggregation operator with intuitionistic linguistic variables is proposed. By means of Matlab, the relation between the intuitionistic fuzzy uncertain linguistic weighted geometric operator K values and the linguistic terms is analyzed at the end of the paper. The results and analysis in this paper provide useful basis for the multiple attribute group decision making, it effectively solves a kind of multiple attribute group decision making problems with the intuitionistic fuzzy uncertain linguistic assessment information.

摘要： 基于零模与共轭零模算子，探讨了直觉模糊不确定语言变量运算法则，得到了基于零模与共轭零模的直觉模糊不确定语言加权几何算子，并给出了一种使用直觉不确定语言变量的集成算子的多属性群决策方法，最后通过Matlab软件分析了直觉模糊不确定语言加权几何算子的K值与语言术语下标间关系。为多属性群决策提供了有价值的参考，有效地解决了一类具有直觉模糊不确定语言评估信息的多属性群决策问题。
