基于熵权法改进的航班延误影响因素评估研究

随着航空运输业的不断发展,航班延误问题越来越受到重视,已成为社会的热点问题.通过实际运行的相关统计数据,研究影响航班延误的各项因素,提取主要因子,构建航班延误综合评价指标体系.用熵权法对航班延误的各项影响因子进行客观评价,建立了基于熵权法改进航班延误影响因素的综合评估模型,并利用1 000架次航班实例对模型的有效性进行了验证,研究结果表明评估模型客观、准确、有效.

Evaluation of Influencing Factors of Flight Delay Based on Improved Entropy Weight Method

With the continuous development of the air transport industry,more and more attention has been paid to the problem of flight delay,which has become a hot issue in the society.In this paper,through the actual operation of the relevant statistical data,the study of the factors affecting the flight delays,extraction of main factors,to build a comprehensive evaluation index system of flight delays.Entropy weight method is used to evaluate the influence factors of flight delay.A comprehensive evaluation model of flight delays based on improved entropy weight method is established.1 000 flights examples was adopted to verify the validity of the model,results show that the evaluation model is objective,accurate and effective.
