Abstract
In this paper, a new approach for handling fuzzy AHP is introduced, with the use of triangular fuzzy numbers for pairwise comprison scale of fuzzy AHP, and the use of the extent analysis method for the synthetic extent value S i of the pairwise comparison. By applying the principle of the comparison of fuzzy numbers, that is, V( M 1 ⩾ M 2) = 1 iff m 1 ⩾ m 2, V( M 2 ⩾ M 1) = hgt( M 1 ∩ M 2) = μ M 1 ( d), the vectors of weight with respect to each element under a certaine criterion are represented by d( A i ) = min V( S i ⩾ S k ), k = 1, 2,…, n; k ≠ i. This decision process is demonstrated by an example.
