This paper proposes a new method for improving the consistency of judgement matrix and gives a simple practical iterative algorithm. The method utilizes the eigenvector of judgement matrix to rectify its column which has maximum error and the corresponding row. It is easy to implement on a computer, and the modified matrix retains most information that original matrix contains.
