In this paper we generalize some classical factorizations of a fuzzy relation into a symmetric component (indifference) and an asymmetric and regular component (regular fuzzy strict preference). From the above notions, we establish two properties of any regular fuzzy strict preference of a max-∗-transitive fuzzy relation, which are then used to obtain new fuzzy versions of Gibbard’s oligarchy t...

The problem of ®nding a solution set of alternatives when a linguistic preference relation represents a collective preference is analyzed following two research lines, choice functions and mechanisms. Four classical choice sets of alternatives for a linguistic preference relation are presented and some relations between them are pointed out. The concept of linguistic choice function as a tool t...

Shoham, proposed, a uniform approach to systems for nonmonotonic reasoning, which consists in considering standard logics augmented with a preference relation on the interpretations. Circumscription can easily -seen. to be a special case of this preference logic framework, but capturing default logic turned out to-be, more difficult, and is even thought to be impossible by some researchers of n...

The concept of revealed preferences surfaces quite often in methodological debates over behavioral economics. There seems to be a close linkage between economists’ attitudes to the revealed preference principle and the opinions that they hold regarding paternalistic policies, or their relative evaluation of decision models. This chapter is an attempt to clarify several aspects of this linkage. ...

Household survey data consistently depict large variations in saving and wealth, even among households with similar socio-economic characteristics. Within the context of the life cycle hypothesis, families with identical lifetime resources might choose to accumulate different levels of wealth for a variety of reasons, including variation in time preference rates, risk tolerance, exposure to unc...

The priority method on the intuitionistic fuzzy preference relation (IFPR) is proposed. In order to avoid the operational difficulty in dealing with the intuitionistic sets, the equivalent interval matrices of the IFPR are introduced. Based on the multiplicative consistent definition of the fuzzy interval preference relation (FIPR), the goal programming models for deriving the priority vector o...

In this paper we develop a language for representing complex qualitative preferences among problem solutions. We use ranked knowledge bases to represent prioritized goals. A basic preference description, that is a ranked knowledge base together with a preference strategy, defines a preference relation on models which represent problem solutions. Our language allows us to express nested combinat...

This paper presents results from a self-paced reading experiment in Japanese investigating attachment preferences for relative clauses to three ensuing potential nominal heads. Similar to previous results from the processing of English, Spanish and German, we observed the following non-monotonic preference ordering among the three attachment sites: most local, least local, intermediate. We disc...
