“…We show, first, that a linear aggregation of criteria values leads essentially to wrong results, thus such methods as the Analytic Hierarchy Process (AHP) [1], [2] should never be applied in serious problems. This results from the Korhonen paradox [3]: a young man considers three candidates for marriage, evaluated based on such criteria as "intelligence" 1 and "sex appeal". The first candidate received 10 points for sex appeal and 0 points for intelligence.…”

The paper addresses the issue of multiple criteria rankings of infrastructural projects (buildings, roads, etc.). Although the amount of literature devoted to this subject is considerable, all methods proposed produce subjective rankings, dependent on a direct or indirect deﬁnition of weighting coeﬃcients applicable to subsequent evaluation criteria. Infrastructural projects are usually selected and approved collegially, however, by a group of decision makers with preferences that may potentially diﬀer signiﬁcantly. Therefore, an objectiﬁed ranking, independent from subjectively deﬁned weighting coeﬃcients, is needed for infrastructural projects. Such a ranking is proposed, analyzed and applied by the authors of this paper. This ranking depends originally only on the multiple objective evaluation data, i.e. the values of evaluation criteria related to decision scenarios or alternatives. Such an approach does not render a fully objective ranking, since one of this kind does not exist at all. Even the choice of the ranking method is a subjective decision, but it is objectiﬁed to the extent possible. The paper presents several examples of multiple criteria evaluation of infrastructural projects, derived from literature, and compares subjective rankings published in literature with objectiﬁed rankings that are independent of weighting coeﬃcients.
