摘要：This paper applied the interval AHP to analyze the problems of consistency and weights of interval judgment matrixes in group decision, and applied the models of the least upper approximation and the greatest lower approximation based on interval regression analysis to solute them, and showed the differences between the two models in application by numerical analysis. In order to reduce the uncertainty in ranking weights, the study applied the weight possible value model to obtain the approximate estimate of interval weight, and then combined with the interval weight, which provided more objective and rational decision-making bases for decision maker.
