| Abstract: | This paper studies the sorting algorithm of triangular fuzzy number for elements of the reciprocal judgment matrix in fuzzy analytical hierarchy process and proposes improved fuzzy probability algorithm. The paper estimates and corrects the satisfied consistency of reciprocal judgment matrix under the improved satisfied consistency index, and uses the fuzzy probability algorithm to transfer feature vector of the triangular fuzzy number judgment matrix into exact value,with a consequence of getting sort vector. The results from analyzing examples show that sort vector approaches to ideal judgment and the algorithm are more accurate. |
