Abstract
Aiming at the problem that the decision-making basis of heterogeneous information cannot be effectively integrated, this paper proposes a decision-making basis integration of heterogeneous information based on evaluation results. Firstly, the idea of maximizing the total deviation between the evaluation values of the evaluation objects by multiple single evaluation methods is used to construct the decision-making method fusion model based on the deviation maximization method. The decision-making basis fusion results of each evaluation object are calculated and sorted. Secondly, Spearman correlation coefficient is adopted to analyze the stability of the fused evaluation value. Finally, by combining the analysis in this study with a comparative analysis from previous paper, the results showed the scientific validity and effectiveness of the fusion method.
