Consensus degrees under fuzzy majorities and fuzzy preferences using OWA (ordered weighted average) operators

The user of Yager’s OWA (ordered weighted average) operators is proposed for handling fuzzy linguistic quantifiers (many, most, almost all,...) used for the formalization of a fuzzy majority in the derivation of a degree of consensus under fuzzy preferences. The idea of a degree of consensus proposed in the authors’ works is employed in which the classical Zadeh’s and Yager’s fuzzy-logic-based calculi of linguistically quantified proposition have been employed. The use of the OWA operators makes it possible to redefine these degrees of consensus with simplicity and intuitive appeal.
