针对大型繁忙机场交通冲突频发、起飞延误等问题,在战略和战术层面分别对机场场面滑行路径规划方法展开研究。简化了机场路网结构,将滑行路径规划与进离场序列结合,建立了航空器总体滑行耗时最短,延误最少的动态优化模型。在比较了流行的机场滑行路经规划算法基础上,从战术规划的角度提出了一种新的基于A~*算法的场面滑行动态规划方法和冲突解脱策略。案例仿真结果表明该方法可以快速有效的减少航空器总体滑行时间和解决滑行冲突,实现机场场面运行效率提升和机场运营的自动化。
In view of the frequent traffic conflicts and take-off delays at large and busy airports, this paper studies the taxiway path planning methods at the strategic and tactical levels respectively. The airport network structure is simplified. Combining the planning of taxiway with the sequence of departure and departure, a dynamic optimization model is established to minimize the aircraft taxiing time and minimize the delay. Based on the comparison of the popular airport taxi route planning algorithm, a new dynamic scheduling method and collision release strategy based on A * algorithm are proposed from the perspective of tactical planning. The case simulation results show that this method can reduce the overall taxiing time and solve the taxi collision effectively and efficiently, and realize the airport scene operation efficiency improvement and the airport operation automation.
