| Abstract: | Aiming at the data quality problem in group evaluation,the outlier data processing is carried out from the perspectives of evaluation experts and evaluation values,and a data quality improvement method based on the degree of grey incidence and cloud model is proposed.Based on the improved cloud distance model,the gap between the evaluated object cloud and the target cloud is measured,and the TOPSIS method is used for ranking.The data quality improvement method and cloud distance algorithm are applied to group evaluation of the regional logistics competitiveness,which improves the data quality of the group evaluation and enhances the stability and representativeness of the evaluation results. |
