Aggregation of individual rankings through fusion functions: criticism and optimality analysis
Bustince Sola, Humberto
; Bedregal, Benjamin ; Campión Arrastia, María Jesús ; Silva, Ivanoska da; Fernández Fernández, Francisco Javier ; Induráin Eraso, Esteban ; Raventós Pujol, Armajac ; Santiago, Regivan (IEEE, 2020)
Artículo / Artikulua 
Throughout this paper, our main idea is to analyze from a theoretical and normative point of view different methods to aggregate individual rankings. To do so, first we introduce the concept of a general mean on an abstract ... -
Decomposition and arrow-like aggregation of fuzzy preferences
Raventós Pujol, Armajac ; Campión Arrastia, María Jesús ; Induráin Eraso, Esteban (MDPI, 2020)
Artículo / Artikulua
We analyze the concept of a fuzzy preference on a set of alternatives, and how it can be decomposed in a triplet of new fuzzy binary relations that represent strict preference, weak preference and indifference. In this ... -
Fuzzy Arrovian theorems when preferences are strongly-connected
Raventós Pujol, Armajac (University of Sistan and Baluchestan, 2022)
Artículo / Artikulua
In this paper we study the aggregation of fuzzy preferences on non-necessarily finite societies. We characterize in terms of possibility and impossibility a family of models of strongly-connected preferences in which the ... -
Geometrical aggregation of finite fuzzy sets
Campión Arrastia, María Jesús ; García Catalán, Olga Raquel ; Induráin Eraso, Esteban ; Lizasoain Iriso, María Inmaculada ; Raventós Pujol, Armajac ; Valero, Óscar (Elsevier, 2018)
Artículo / Artikulua
A fuzzy set on a finite universe can be interpreted as a vector in a unit cube. This gives rise to a huge variety of approaches in order to aggregate finite fuzzy sets or to modify a given one. We analyze several geometrical ... -
Multidistances and inequality measures on abstract sets: an axiomatic approach
Campión Arrastia, María Jesús ; Díaz, Irene; Induráin Eraso, Esteban ; Martín, Javier; Mayor, Gaspar; Montes Rodríguez, Susana; Raventós Pujol, Armajac (Elsevier, 2021)
Artículo / Artikulua
Starting from the notion of a multidistance, we formalize, through a suitable system of axioms, the concept of an inequality measure defined on a nonempty set with no additional structure implemented a priori. Among ... -
A survey on the mathematical foundations of axiomatic entropy: representability and orderings
Campión Arrastia, María Jesús ; Gómez Polo, Cristina ; Induráin Eraso, Esteban ; Raventós Pujol, Armajac (MDPI, 2018)
Artículo / Artikulua
Different abstract versions of entropy, encountered in science, are interpreted in the light of numerical representations of several ordered structures, as total-preorders, interval-orders and semiorders. Intransitivities, ... -
Topologies for semicontinuous Richter–Peleg multi-utilities
Bosi, Gianni; Estevan Muguerza, Asier ; Raventós Pujol, Armajac (Springer, 2020)
Artículo / Artikulua
The present paper gives a topological solution to representability problems related to multi-utility, in the field of Decision Theory. Necessary and sufficient topologies for the existence of a semicontinuous and finite ...
