Choosing and Ranking on the Basis of Fuzzy Preference Relations with the "Min in Favour"
نویسنده
چکیده
In some MCDM techniques Ð most notably in Outranking Methods Ð the result of the comparison of a finite set of alternatives according to several criteria is summarised using a fuzzy preference relation. This fuzzy relation does not, in general, possess "nice properties" such as transitivity or completeness and elaborating a recommendation on the basis of such information is not an obvious task. The purpose of this paper is to study techniques exploiting fuzzy preference relations in order to choose or rank. We present a number of results concerning techniques based on the "min in Favour" score, i.e. the minimum level with which an alternative is "at least as good as" all other alternatives.

A Quadratic Programming Method for Ranking Alternatives Based on Multiplicative and Fuzzy Preference Relations
This paper proposes a quadratic programming method (QPM) for ranking alternatives based on multiplicative preference relations (MPRs) and fuzzy preference relations (FPRs). The proposed QPM can be used for deriving a ranking from either a MPR or a FPR, or a group of MPRs, or a group of FPRs, or their mixtures. The proposed approach is tested and examined with two numerical examples, and compara...

متن کاملRanking triangular interval-valued fuzzy numbers based on the relative preference relation
In this paper, we first use a fuzzy preference relation with a membership function representing preference degree forcomparing two interval-valued fuzzy numbers and then utilize a relative preference relation improved from the fuzzypreference relation to rank a set of interval-valued fuzzy numbers. Since the fuzzy preference relation is a total orderingrelation that satisfies reciprocal and tra...
متن کاملCREDIBILITY THEORY ORIENTED PREFERENCE INDEX FOR RANKING FUZZY NUMBERS
This paper suggests a novel approach for ranking the most applicable fuzzy numbers, i.e. $LR$-fuzzy numbers. Applying the $alpha$-optimistic values of a fuzzy number, a preference criterion is proposed for ranking fuzzy numbers using the Credibility index. The main properties of the proposed preference criterion are also studied. Moreover, the proposed method is applied for ranking fuzz...
متن کاملA Note on the ‘min in Favor’ Choice Procedure for Fuzzy Preference Relations
This note deals with the problem of choosing on the basis of a fuzzy preference relation. In the area of MCDM, such a problem occurs with outranking methods using fuzzy relations such as ELECTRE III. In this note, we study a choice procedure based on the ‘min in favor’. We show that it is the only one to satisfy a system of three independent axioms.
