Using intuitionistic fuzzy sets in group decision making

: The determination of solutions in group decision making via intuitionistic fuzzy sets is considered. The point of de parture is a collection of individual intuitionistic fuzzy preference relations. We also assume a (traditional) fuzzy majority equated with a fuzzy linguistic quantifier. A solution is derived either di rectly from the individual intuitionistic fuzzy preference relations or by constructing first a social intuitionistic fuzzy preference relation. Two solution concepts are proposed, intuitionistic fuzzy core and consensus winner.
