Some Construction Methods for Pseudo-Overlaps and Pseudo-Groupings and Their Application in Group Decision Making

In many real-world scenarios, the importance of different factors may vary, making commutativity an unreasonable assumption for aggregation functions, such as overlaps or groupings. To address this issue, researchers have introduced pseudo-overlaps and pseudo-groupings their corresponding non-commutative generalizations. paper, we explore various construction methods obtaining using overlaps, groupings, fuzzy negations, convex sums, Riemannian integration. We then show applicability these in a multi-criteria group decision-making problem, where both considered criteria experts vary. Our results highlight usefulness alternative to
