Fermatean fuzzy set theory is emerging as a novel mathematical tool to handle uncertainties in different domains of real world. sets were presented order that uncertain information from quite general real-world decision-making situations could be mathematically tractable. To purpose, these are more flexible and reliable than intuitionistic Pythagorean sets. This paper presents hybrid model, nam...

Multiattribute decision making involves tradeoffs among alternative performances over multiple attributes. The accuracy of performance measures are usually assumed to be accurate. Most multiattribute models also assume given values for the relative importance of weights for attributes. However, there is usually some uncertainty involved in both of these model inputs. Outranking multiattribute m...

This paper deals with preference representation and decision-making problems in the context of multiattribute utility theory. We focus on the generalized additive decomposable utility model (GAI) which allows interactions between attributes while preserving some decomposability. We present procedures to deal with the problem of optimization (choice) and ranking of multiattribute items. We also ...
