Abstract

Literature of aggregation operators defined in the domains of linguistic and interval-valued linguistic information is extensive and vast. But, some operators are not well-defined and do not benefit the researchers. In this paper, we have highlighted the flaws in defining the operators and demonstrated them via examples. Further, some remedial suggestions for the improvement of the definitions are given.

Keywords- Multiple criteria group decision making, 2-tuple linguistic variable, Interval 2-tuple linguistic variable, Aggregation operators.
