The Analytic Hierarchical Process (AHP) determines the relative
importance of a set of alternatives in a multi-criteria decision problem.
AHP has a hierarchial structure and based on pairwise comparisons of
the project alternatives as well as pairwise comparisons of the multi
criteria. Two separate algorithms have been presented for measuring
the inconsistency ratioes of pairwise comparisons matrix and
hierarchical structure. In this paper these algorithms and one of the
approximation methods, have been extended for measuring the
inconsistency ratioes and alternatives’ weights in fuzzy AHP. A
numerical example is used to illustrate these methods.
