Abstract:In order to improve the lack of accuracy of evaluation result caused by the judgment matrix belonged to analytic hierarchy process (for short,AHP),constructed an objective judgment matrix indicating relative dependence among attributes by using definition of attribute dependence in rough set theory.Then proposed a new evaluation method that make decision by calculating the weight of the combinatorial judgment matrix which was formed by combining the objective judgment matrix and the subjective judgment matrix of AHP.Finally,an example suggests the higher decision accuracy, feasibility and effectiveness of this comprehensive method.Moreover,it is easy to be promoted in practical application.......
