Existence of a positively homogeneous and translation invariant continuous certainty equivalent.
The notion of a construction of a fuzzy preference structures is introduced. The properties of a certain class of generated fuzzy implications are studied. The main topic in this paper is investigation of the construction of the monotone generator triplet , which is the producer of fuzzy preference structures. Some properties of mentioned monotone generator triplet are investigated.
In the article the formal characterization of preference spaces [1] is given. As the preference relation is one of the very basic notions of mathematical economics [9], it prepares some ground for a more thorough formalization of consumer theory (although some work has already been done - see [17]). There was an attempt to formalize similar results in Mizar, but this work seems still unfinished [18]. There are many approaches to preferences in literature. We modelled them in a rather illustrative...
El objetivo de este trabajo es el estudio de los juegos no cooperativos en los que los jugadores expresan sus preferencias sobre las consecuencias que se derivan de sus acciones mediante relaciones binarias difusas. El concepto de solución que se maneja es el de estrategias en equilibrio. La existencia de tales estrategias queda probada en el caso de que los jugadores definan sus preferencias sobre las consecuencias aleatorias mediante la extensión lineal introducida en Montero-Tejada (1986a).
On se propose d'établir et d'analyser l'opinion collective d'une assemblée d'individus auxquels il a été demandé de lire puis de juger quinze extraits d' œuvres littéraires présentés sans titre ni nom d'auteur. Les évaluations portées par chaque juge sont converties en préférences individuelles que l'on traite ensuite au moyen d'une méthode combinatoire. L'établissement d'un ordre de préférence collectif ne constitue pas le but de cette étude, mais plutôt son point de départ ; il ne s'agit pas,...
In this paper we deal with mathematical modeling of real processes that are based on preference relations in the sense that, for every pair of distinct alternatives, the processes are linked to a value of preference degree of one alternative over the other one. The use of preference relations is usual in decision making, psychology, economics, knowledge acquisition techniques for knowledge-based systems, social choice and many other social sciences. For designing useful mathematical models of such...
L'évaluation multicritère est un problème bien connu souvent traité par des méthodes de surclassement. Nous avons ici envisagé le cas général de plusieurs juges et agrégé les différentes évaluations pour construire une matrice de préférences, ramenant ainsi le problème à un problème de comparaisons par paires. Nous avons cherché des solutions optimales de classement en appliquant un algorithme d'affectation quadratique particulier.
In decision processes some objects may not be comparable with respect to a preference relation, especially if several criteria are considered. To provide a model for such cases a poset valued preference relation is introduced as a fuzzy relation on a set of alternatives with membership values in a partially ordered set. We analyze its properties and prove the representation theorem in terms of particular order reversing involution on the co-domain poset. We prove that for every set of alternatives...
