Properties of the aggregation operators related with fuzzy relations

Abstract The problem of information generalization in multicriteria decision making is considered in this paper. The information is unified by fuzzy relations and the generalization is realized with the help of aggregation operators. Some of the most oftenly used operators are presented and their properties depending on the properties of the fuzzy relations, which they aggregate, are proved. The sensitivity of the operators with respect to variations in their arguments is investigated. The numerical example deciding the problem of alternatives’ ranking is given as well.
