Some Methods of Raising Exactness of Evaluation in AHP
提高层次分析法评价精度的几种方法

In order to raise evaluating exactness of AHP, in this paper, some important problems in AHP such as method of survey, selection of scale, constructing pairwise comparison matrix and analysis of rank reversal problem, etc. have been studied, and some improving method for each problem has been proposed. It will provide an effective and practical reference method for theoretical and practical workers on raising exactness and dependability of evaluation in utilizing AHP.
