Generalized Interval-Valued Intuitionistic Trapezoidal Fuzzy Priority Weighted Geometric Operator and Its Applications

针对决策指标和决策者不在同一优先级下的区间直觉梯形模糊多属性决策问题,提出了广义区间直觉梯形模糊优先级加权几何算子,并推导出其数学表达式,研究了该算子的相关性质和一些特例,探讨了基于广义区间直觉梯形模糊优先级几何算子的多属性群决策方法;最后给出数值实例证明了算子的有效性。

In view of the multi-attribute decision making problem existing in the interval valued intuitionistic trapezium with decision index and decision maker at different priority levels,a proposal has thus been made of a generalized interval valued intuitionistic trapezoidal fuzzy priority weighted geometric operator,followed by the derivation of the mathematical expressions,as well as a further study on the related properties and some special cases of the operator.Meanwhile,an investigation is to be made of the multi-attribute group decision making method based on generalized interval valued intuitionistic trapezoidal fuzzy priority geometric operators.Finally,a numerical example is given to verify the validity of the operator.
