Abstract

This paper presents that the consistency test with consideration of a tolerance deviation in fuzzy AHP proposed by L. C. Leung and D. Cao 2000 is not efficient and has some errors, hence a new method of fuzzy consistency test by direct fuzzification of Quick Response QR algorithm-which is one of numerical methods for calculating eigenvalues of an arbitrary matrix-has been proposed.
