摘要：A multicriteria decision making problem with criteria giving fuzzy relations between the couples of alternatives is considered. The importance of each of the criteria is given as weighting function depending on the membership degrees of the corresponding fuzzy relation. Transformed membership degrees with the help of these weighting functions are used in the aggregation procedure for fusing the relations. The properties of the weighted relations, required to decide the problems of choice, ranking or clustering of the alternatives’ set are proved. An illustrative numerical example solving the problem of alternatives’ ranking is presented as well.
