GSES Using Interval 2-Tuple Linguistic Distance Operators

With respect to multi-criteria GSES problems with interval 2-tuple linguistic information, a new approach that uses distance measures is proposed in this chapter. Motivated by the ordered weighted distance (OWD) measures, we develop some interval 2-tuple linguistic distance operators such as the interval 2-tuple weighted distance (ITWD), the interval 2-tuple ordered weighted distance (ITOWD), and the interval 2-tuple hybrid weighted distance (ITHWD) operators. These aggregation operators are very useful for the treatment of input data in the form of interval 2-tuple linguistic variables. We study some desirable properties of the ITOWD operator and further generalize it by using the generalized and the quasi-arithmetic means. Finally, the new approach is utilized to complete a green supplier selection study for an actual hospital from the healthcare industry.
