Multi-criteria group decision making based on trapezoidal intuitionistic fuzzy information
We propose a new trapezoidal intuitionistic fuzzy MCGDM model. The mean consistency degree of alternative is defined based on TrIFWA operator. A group consistency degree considering the importance of alternative ranking position is defined. A group consistency analysis and correction procedure is developed.
