Computing a consistent approximation to a generalized pairwise comparisons matrix. (English) Zbl 0936.65057

The authors introduce an algorithm of complexity \(O(n^2)\) for computing a consistent approximation to a generalized pairwise comparisons matrix. The algorithm is based on a logarithmic transformation of the matrix into a linear space with the Euclidean metric. It uses both the row and (reciprocals of) column geometric means. The resulting approximation is optimal and consistent.
