Abstract: The Edgeworth–Pareto principle is extended to the class of multicriteria choice problems, in which the preference relation of the decision maker is described by a type-2 fuzzy binary relation. The necessary condition for its fulfillment is the adoption of two assumptions: the Pareto axiom and axiom of exclusion of dominated variants. Brief information about fuzzy sets and relations of types 1 and 2 precedes the main results of the paper. In order to justify the Edgeworth–Pareto principle a fuzzy set of nondominated variants is introduced in the case of a type-2 fuzzy preference relation.
