Abstract: Aimed at the problem of comprehensive evaluation to pull the greatest degree of difference between evaluation objects, through analyzing the limitations existing in linear deviation maximization method, this paper proposes a nonlinear deviation maximization method based on comprehensive judgment of subject and object information,in order to further enrich and improve the theoretical knowledge of deviation maximization method. Firstly, we give a brief introduction to the linear deviation maximization method and analyze the limitation. Secondly,we develop the research hypotheses and give the nonlinear factor selection principle and the method to determine the index order,and give the method to select the adjacent index important degree ration after ordering. According to the principle of evaluation, we use the planning model to calculate every index’s weight,and also use the nonlinear aggregation model to calculate the final evaluation results. Finally, we give a numerical example to verify the effectiveness of the method.
