Abstract :
A general form of a collective choice rule in group decision making under fuzzy preferences and a fuzzy majority is proposed. It encompasses some well known choice rules. Our point of departure is the fuzzy majority-based linguistic aggregation rule (solution concept) proposed by J. Kacprzyk (1985, 1986). This rule is viewed in this paper from a more general perspective, and the fuzzy majority - meant as a fuzzy linguistic quantifier - is dealt with by using R.R. Yager´s (1988) ordered weighted averaging (OWA) operators. The particular collective choice rules derived via the general scheme proposed are shown to be applicable in the case of non-fuzzy preferences too
