Fuzzy Prisoner’s Dilemma

A. Kandel. University of South Florida

Y-Q. Zhang. Georgia Southwestern State University

P.S.S. Borges. Federal University of Santa Catalina (BRAZIL)

In this paper, the global prisoner's dilemmas are introduced and extensively analyzed. This variation from the traditional game consists in allowing the players to combine, with variable emphasis, both selfish and philanthropic goals. Through analyzing the various kinds of precise and fuzzy global prisoner's dilemmas, we have found that some…

New estimation methods in fuzzy regression analysis, based on projection theorem and decoupling principle

V. Georgescu University of Craiova

In this paper we introduce a new formal criterion, named the decoupling principle, which allows us to naturally extend the projection theorem into a fuzzy regression framework. This criterion justifies a radical revision of the usual estimation methods. It should be mentioned here that actually dominant in the fuzzy regression…

The use of the preference disaggregation analysis in the assessment of financial risks

M. Doumpos, C. Zopounidis. Technical University of Creta

Multicriteria decision aid (MCDA) provides several methodologies which are well adapted in the assessment of financial risks which are best studied from the sorting point of view. A well known approach in MCDA is based on preference disaggregation, which has already been used in ranking problems, but it is also…

Preliminary aspects on the development of a choice method for determining a best fitting case dependent fuzzy transitivity definition

E. E. Haven. Consortium McGill University

The choice of a fuzzy transitivity definition is in many instances case dependent. We propose in this paper a method which may help us reveal which choice of fuzzy transitivity definition may be preferred over another, in the event there exists a crisp linear ranking. If we have criteria varying…

Fuzzy methods and infeasible linear programs: an application to staff design problems

T. León, V. Liern. Universidad de Valencia

In this paper we are concerned with infeasibility in Linear Programming. In real-life problems this situation is not so strange, specially when new strategies or policies are being considered. We summarize the most usual crisp techniques to approach this question and finally, by means of a case study, we propose…
