Some Issues on Consistency of Fuzzy Analytic Hierarchy Process

This study presents a fuzzy analytic hierarchy process (FAHP) model based on consistent fuzzy linguistic preference relations to deal with consistency. The proposed method yields decision matrices for making pairwise comparisons using additive transitivity. Only n-1 comparison judgments are required to ensure consistency on a level that contains n criteria. Finally, a practice example is compared with the proposed method and FAHP method. The proposed method is simple and more accuracy than FAHP method
