Multi-criteria group decision-making method based on intuitionistic trapezoidal fuzzy information
Jian‐qiang Wang, Rongrong Nie · Systems Engineering - Theory & Practice · 2012
With respect to the limitations in existing papers,the new arithmetic operations of intuitionistic trapezoidal fuzzy numbers are defined.Then some aggregation operators of intuitionistic trapezoidal fuzzy numbers as well as their properties are proposed.The proposed aggregation operators are applied into the group decision making problems and a solution method is developed.In the end,a numerical example is illustrated to show the proposed decision making method's effectiveness and rationality.
