Clusters and pivots for evaluating a large numberof alternatives in AHP

Abstract: ABSTRACT. AHP has been successful in many cases but it has a major limitation: a larger number of alternatives requires a high number of judgements in the comparison matrices. In order to reduce this problem, we present a method with clusters and pivots. This method also helps with a further four problems of the Analytic Hierarchy Process. It enlarges the comparison scale, facilitates the construction of a consistent or near consistent matrix, eliminates the problem of the choice of the priorities derivation m… Show more

“…In the present paper, for the structuring of the pairwise comparison matrix (step (3)) will be applied: (i) for quantitative criteria analysis, a full aggregation approach; (ii) for qualitative criteria analysis, to solve the problem of a large number of pairwise evaluations, the traditional AHP procedure has been implemented according to the cluster approach and pivots approach [23] as synthesized by Ishizaka and Nemery [5].…”
