Abstract: This paper studies the group decision-making methods in AHP and their applications in the evaluation of enterprise credit, establishes two kinds of weighted distance methods, where the preferences of expeds or decision-makers and the believable degrees of the judgement matrices given by the experts or decision-makers are reflected, and, as the result,the influence of the experts or the decision-makers’ opinion on the evaluation result is reflected effectively both in subjective aspect and in objedive aspect. The evaluation of enterprise credit is one of the most important works in the risk management of the bank’s credit.The exact evaluation of the grade of each enterprise credit depends on a lot of corresponding factors, which needs the comprehensive evaluation of the experts from various corresponding fields.The reasonable evaluation result should reflect not only the degree of each expert or decision-maker’s knowing of the state of each enterprise and the credit risk, but tbe believable degree of each judgemnt matrix given by experts or decision-makers as well. This poper solves the above problem effectively by establishing the weighted distance methods where the weight coefficients placed in the methods are detendned by their preferences and the believable degree of judgement matrices.

Key words: AHP, group evaluation, credit evaluation, credit risk
