We focus on the Ferrers property of fuzzy preference relations. We study the connection between the Ferrers property and fuzzy interval orders. A crisp total interval order is characterized by the Ferrers property of its strict preference relation. Also, a crisp preference structure is a total interval order if and only if its large preference relation satisfies the Ferrers property. For fuzzy ...

For the formal expression of uncertain data, hesitant fuzzy set theory has established itself as a distinguished model because it broad use in multi-attribute decision-making problems. With incorporation features from N-soft sets, useful framework referred to sets acquired an even greater appeal. This integrates and associates environment with information regarding existence grades or star rati...

Ranking and selecting projects is a relatively common, yet often difficult task. It is complicated because there is usually more than one dimension for measuring the impact of each project and more than one decision maker. This paper considers a real application of project selection for ECNZ, Northern Generation, using an approach called ELECTRE. The ELECTRE method has several unique features n...
