摘要: 随着机场航班密度逐渐增加,相同停机位、相邻航班发生冲突的可能性不断增大,从而影响机场的运行效率,增加停机位运行风险。 基于双层规划模型,以远机位使用率和停机位分配鲁棒性作为上层模型的优化目标,以相同停机位、相邻航班推出冲突时间作为下层模型的优化目标,对停机位分配冲突进行优化,利用遗传算法来寻求整个系统的最优解。 选择某机场的实际航班数据进行算例分析,结果表明:优化后,早晚高峰时段的远机位使用分别降低了 31.25%和 23.53%,冲突时间分别减少了 16 min 和 24 min,提高了停机位利用率和机场运行效率,同时有效降低停机位运行风险,可为大型繁忙机场的停机位利用率和运行效率提升、停机位运行风险降低提供解决方案和技术支持。

Abstract: With the gradual increase of airport flight density, the possibility of conflict between adjacent flights at the same gate is increasing, which affects the operational efficiency of the airport and increases the gate operation risks. Based on bi-level programming model, this paper takes far airport gate utilization and robustness of airport gate assignment as the upper model of the optimization goal, takes push-out conflict time of adjacent flights at the same gate as the lower model of the optimization goal, to optimize airport gate assignment, and employs the genetic algorithm to find the optimal solution of the whole system. The actual flight data of an airport is selected for example analysis. The results show that the use of remote seats in morning and evening peak hours was reduced by 31.25% and 23.53% respectively, and the conflict time was reduced by 16 minutes and 24 minutes after optimization, improving the utilization rate of airport gate assignment and the airport operating efficiency. The study provides solutions and technical support for large and busy airport operation and effectively reduces the risks of gate operation.

Key words: airport, airport gate conflict, bi-level programming model, genetic algorithm (GA), operational efficiency, oper鄄 ational risks
