Abstract: For a mass evaluation which is carrying out with a large number of experts (stakeholders) participating in it, a method is proposed to balance the discrepancy and consistency in evaluation results, representing diverse alternatives to highlight the discrepancy as much as possible and reasoning out a conclusion in which the consistency will be acceptable to all participants. In this method the discrepancy between different alternatives is enabled to the utmost extent and all the alternatives are divided according to the stabilized discrepancy, thus ensuring the consistency of evaluation results that were given by different participants whose alternatives were of the same category. Then, the information between different categories are aggregated according to the generic influence so as to reach a conclusion of consistency acceptable to all participants. An application example is given to illustrate the validity of this method.
