Abstract

The use of Yager’s (1988) OWA (ordered weighted average) operators is proposed for handling fuzzy linguistic quantifiers (many, most, almost all,... ) which are used for the formalization of a fuzzy majority in the derivation of a “soft” degree of consensus under fuzzy preferences proposed in the authors’ works (Fedrizzi, 1988; Kacprzyk, 1987; Kacprzyk and Fedrizzi, 1986, 1988, 1989) in which the classical Zadeh’s (1983) and Yager’s (1983) fuzzy-logic-based calculi of linguistically quantified proposition were employed. It seems that the use of the OWA operators can contribute to a high computational efficiency and intuitive appeal.
