基于改进群组层次分析法的机场Ⅱ/Ⅲ类运行效益影响因素研究

为研究运输机场Ⅱ/Ⅲ类运行效益影响因素，参考相关规则及机场调研建立了Ⅱ/Ⅲ类运行效益影响因素指标体系，采用群组层次分析法，通过改进打分方式和k均值聚类算法对其进行优化。对比改进前后两种方法得出的指标权重结果，发现改进的群组层次分析法得出的权重差异明显，适合关键影响因素提取。最后分析场地改造、灯光系统升级改造等关键影响因素，对国内Ⅱ/Ⅲ类运行建设效益问题给出了相关建议。

Research on factors influencing airport Category II/III operation benefit based on improved group analytic hierarchy process

In order to study the influencing factors of Category II/III operational efficiency of transportation airports, an index system regarding the factors influencing the Category II/III operation efficiency is established refering to the relevant regulations as well as airport surveys, and the group Analytic Hierarchy Process (AHP) is adopted to optimize it by improving the scoring method and k-means clustering algorithm. The comparison of the index weight results obtained using the methods before and after the improvement show that the weight obtained via the improved group AHP is considerably different, which is suitable for extracting key influencing factors. Finally, the key influencing factors, such as site transformation and lighting system upgrading, are analyzed and relevant suggestions are proposed for the benefit of Category II/III operation and construction in China.
