A new uncertainty comparison matrix—three-point interval number comparison matrix is put forward and its consistency and weight estimation approach are studied.Based on the complete consistency definition of three-point interval number comparison matrix,the possible value error and the upper- low error are defined.Following that,a weight model of three-point interval number com- parison matrixes is proposed.In second stage,a weight low-upper region estimation model is devel- oped to solve the misleading problem owing to the judgment error of decision maker.The properties of these models are studied.In the last,the model validity is demonstrated by examples.
