A lattice-theoretic framework for hesitant fuzzy convexity beyond scalar observables
Carlos Salvatierra, Pedro Huidobro, Raquel Fernandez-Peralta
In fuzzy-set theory, the notion of convexity has often been formulated through scalar reductions, typically via scores and aggregation functions. Although useful, such reductions m…

An order-oriented approach to scoring hesitant fuzzy elements
Luis Merino, Gabriel Navarro, Carlos Salvatierra +1
Traditional scoring approaches on hesitant fuzzy sets often lack a formal base in order theory. This paper proposes a unified framework, where each score is explicitly defined with…
