ABSTRACT
This study proposes some extended aggregation operators to model Extreme Conformity and Bounded Extreme Conformity which were proposed in a recent work. In detail, we propose Interval Judged s-t-A extreme operators and Selective Leveled-Preferences Ordered Weighted Averaging operators, respectively, and analyze some of their properties such as the related degenerations and monotonicities. Both types of operators have more flexibility and adjustability. An application of Interval Judged s-t-A extreme operators in project evaluation and decision-making is also introduced.
