The problem originates from multicriteria decision making, where aggregation procedures realized the way for compensation between some evaluations. The quasi–linear means will be taken as aggregation functions. The author will make an attempt at answering two questions\: does relation R obtained by aggregation of relations Ri have the same kind of ∗–transitivity as basic relations\? If we don’t obtain a positive answer, we will try to investigate which ∗–transitive class of relation do the results of aggregation belong to\? T–norms will be taken as ∗."]
