Procedimento de redução das avaliações do AHP por transitividade da escala verbal de SAATY

Abstract

AHP is a decision support method that requires the collection of pairwise evaluations between the variables of the problem. Depending on the hierarchical structure and the number of variables, the effort required to collect these judgments becomes excessive, involving a workload almost impracticable for using the method in complex problems. This article provides a practical and simple procedure for reducing this effort, making AHP attractive to real cases. The method is based on the transitivity of the AHP verbal scale. The results indicated that the proposed procedure brings logical consistency to incomplete evaluations and, even in cases where this consistency exceeded the threshold of 10%, new rounds of evaluations would not be necessary.
