考虑巡航速度调整的航班恢复优化模型

Aircraft Routing Recovery Model with Cruise Speed Control

在现有航班恢复的文献中,往往只考虑航班取消、航班延误和飞机交换恢复策略,但航空公司实际运行中还会用到巡航速度调整,因此本文在考虑巡航速度调整的基础上建立航班恢复模型,并运用MATLAB结合收集到的航班数据进行算例求解。结果表明:优化方案与手动顺延方案相比,恢复成本降低65.40%,恢复效率提高51.39%;与历史方案相比,恢复成本降低28.82%,恢复效率提高31.43%。并且通过数值分析发现,单位延误成本越高,巡航速度调整降低航班恢复成本的效果越明显。

In the existing literature on flight recovery, often only consider flight cancellation, flight delays and aircraft exchange recovery strategies,but the actual operation of airlines will also use cruise speed adjustment, so this paper establishes the flight based on the cruise speed adjustment Recover the model, and use MATLAB to solve the calculation example with the collected flight data. The results show that compared with the manual postponement scheme, the optimized scheme reduces the recovery cost by 65.40% and the recovery efficiency increases by 51.39%;compared with the historical scheme, the recovery cost reduces by 28.82% and the recovery efficiency increases by31.43%. And through numerical analysis, it is found that the higher the unit delay cost, the more obvious the effect of cruise speed adjustment in reducing flight recovery costs.
