In decision-making models based on the Fuzzy Analytic Hierarchy Process, it is necessary to check the consistency of the fuzzy pairwise comparisons matrices.The consistency of the fuzzy matrix 3x3 can be checked on the basis of the similarity of the fuzzy numbers.In this paper, it is shown how to check the consistency of matrices of larger dimensions by decomposing these matrices to the 3x3 matrices.The consistency check of fuzzy matrices by decomposition is shown for pairwise comparisons matrices obtained by using fuzzified Saaty's scale.The direction for future research is proposed.
