 Some Generalized Dependent Aggregation Operators with Interval‐Valued Intuitionistic Fuzzy Information and Their Application to Exploitation Investment EvaluationXiao-wen Qi, Chang-yong Liang and Junling Zhang Journal of Applied Mathematics, 2013, vol. 2013, issue 1 Abstract: We investigate multiple attribute group decision making (MAGDM) problems with arguments taking the form of interval‐valued intuitionistic fuzzy numbers. In order to relieve influence of unfair arguments, a Gaussian distribution‐based argument‐dependent weighting method and a hybrid support‐function‐based argument‐dependent weighting method are devised by, respectively, measuring support degrees of arguments indirectly and directly, based on which the Gaussian generalized interval‐valued intuitionistic fuzzy ordered weighted averaging operator (Gaussian‐GIIFOWA) and geometric operator (Gaussian‐GIIFOWG), the power generalized interval‐valued intuitionistic fuzzy ordered weighted averaging (P‐GIIFOWA) operator and geometric (P‐GIIFOWA) operator are proposed to generalize a wide range of aggregation operators for decision makers to flexibly choose in decision modelling. And some desirable properties of the proposed operators are also analyzed. Further, application of an approach integrating proposed operators to exploitation investment evaluation of tourist spots has shown the effectiveness and practicality of developed methods; experimental results also verify the properties of proposed operators.
