Abstract: In order to better study the optimization of aircraft taxiing path in the airport, the taxiing process of the aircraft after landing was analyzed, the optimal runway exit taxiway was selected to leave the runway. Combining with the taxiing conflict constraint conditions, the optimization model of aircraft taxiing path was established. The taxiing path optimization algorithm based on the improved genetic algorithm was applied to solve the proposed model. The results of the example analysis show that the global taxi time of the aircraft is reduced and the occupation time of the landing aircraft on the runway is reduced, which shows that the proposed algorithm is feasible.

摘要： 为更好的研究航空器在机场滑行路径优化问题，对航空器在着陆后滑行运动过程进行分析，选择最优的跑道出口滑行道脱离跑道，并结合滑行冲突约束条件建立航空器滑行路径优化模型，采用基于改进遗传算法的滑行路径优化算法对模型进行求解。算例分析结果表明：航空器的全局滑行时间减少，着陆航空器对于跑道的占用时间减少，可见算法可行。
