A New Method for Construction of Judgement Matrix in AHP

In this paper, a new Inethod (Difference method) for constructing judgement matrix is presented. Based on the above construction, it is unnecessary to check the consistency ratio while applying AHP (the Analytic Hierarchy Process) to order, and AHP is more effectual and more sensitive compared with Satty's direct comparative method (Quotient method) on some special occasions. Besides,from the view of methodology, Difference method also enhances the adaptability of AHP.
