基于航空排放的机场停机位分配优化

随着航空业的快速发展,航空排放对大气环境的影响日益严重。机场停机位分配优化研究,对航空绿色发展具有重要意义。基于场面运行规则,航空器排放、近机位利用率等多目标,建立一种使航空器排放量最小,近机位利用率最大的机场停机位分配优化模型,并通过南京禄口国际机场某日航班数据实例验证。结果表明:由于近机位利用率的提升,航空器的HC、NOx、CO、SOx和颗粒物(particulate matter,PM)排放量分别减少12. 33%、7. 81%、12. 66%、11. 06%和11. 17%;地面保障设备(ground support equipment,GSE)的HC、NOx、CO、PM排放量分别减少9. 59%、4. 63%、14. 34%、13. 64%;远机位旅客平均花费时间减少42. 31%。可见提出的优化模型增加了近机位利用率,减少了机场航空排放,减少了远机位旅客平均花费时间,验证了模型有效性。

Study on Optimization of gates assignment based on air emissions

With the development of aviation industry, the impact of air emissions on the atmospheric environment is becoming more serious. The study on optimization of airport gates allocation is of great significance to the development of greener aviation. In this paper, an optimal model was established to minimize aircraft emissions and maximized contact gates utilization based on operation rules, aircraft emissions, utilization rate of contact gate and other objectives. The verification of flight data on a certain day at Nanjing Lukou International Airport shows that: the HC, NO, CO, SOx and PM from aircraft are reduced by 12.33%, 7.81%, 12.66%, 11.06% and 11.17% respectively due to the improvement of near-seat utilization rate, and the HC, NO, CO and PM emissions of GSE are reduced by 9.59%, 4.63%, 14.34% and 13.64%, respectively. The average time spent by passengers to remote gate decreases by 42.31%. The proposed optimization model increases the utilization rate of contact gate, reduces air emissions, and average time spent by passengers and the model is verified.
