A CONSISTENCY IMPROVING METHOD IN BINARY AHP

Abstract

In this paper, a consistency improving of the comparison matrix in binary AHP (Analytic Hierarchy Process) is studied. As its byproducts, we propose a method to count the cycles of length 3 and to find the locations of the cycles in a complete directed graph. We apply our proposed consistency improving method to various examples including three actual sports games. Comparing our method with ordinary improving method, we can show the usefulness of our method.
