摘要
为提高航班在雷雨天气下绕飞改航的安全性和正常率,首先,将空域网格化,考虑气象规避区、航空器性能、油耗等因素,根据航空器的起讫点和出发时间建立一种考虑多重安全因素的航空器雷雨绕飞改航路径规划(ARRPTC)模型,确定航空器在起点的空中盘旋等待时间及起讫点之间的绕飞路径,追求总飞行时间最少;其次,根据问题特征,设计求解该问题的多策略改进蜣螂优化算法(MSDBO),提高算法收敛速度与精度,避免算法陷入局部最优;然后,对比MSDBO与其他4种群体智能算法在6个基准测试函数上的性能,验证改进策略的有效性;最后,以某航空器真实雷雨绕飞为例进行仿真试验。结果表明:该模型相较于传统模型绕飞时间和距离分别减少52.3%和53.0%,总飞行时间和距离分别减少16.5%和14.3%,飞行油耗减少13.6%。与其他4种群体智能算法相比,MSDBO拥有更快的收敛速度、更好的全局探索和局部开发能力;MSDBO在航空器ARRPTC模型中能够求解出更好的飞行航迹,显著提高航班绕飞改航效率;随着雷雨安全阈值和颠簸系数阈值逐渐减小,航空器绕飞路径航程会有所增加。
To enhance the safety and on-time performance of flight rerouting under thunderstorm conditions,the airspace was first discretized into grids.Considering meteorological avoidance zones,aircraft performance,and fuel consumption,an ARRPTC model incorporating multiple safety factors was established based on the aircraft's origin,destination,and departure time.The model determined both the aircraft's airborne holding time at the departure point and its optimal rerouting path,with the objective of minimizing the total flight time.Subsequently,a multi-strategy improved DBO(MSDBO)was designed according to the problem characteristics to improve convergence speed and accuracy while avoiding premature convergence of the algorithm.The performance of the proposed MSDBO was then compared with four other swarm intelligence algorithms by means of six benchmark test functions to verify the effectiveness of the improvement strategies.Finally,a case study based on an actual aircraft rerouting scenario under thunderstorm conditions was conducted.The results indicate that,compared with traditional models,the proposed ARRPTC model reduces the detour time and distance by 52.3%and 53.0%,respectively,while the total flight time and distance decrease by 16.5%and 14.3%,and fuel consumption is reduced by 13.6%.Compared with the other four swarm intelligence algorithms,MSDBO demonstrates faster convergence,stronger global exploration,and superior local exploitation capabilities.In the ARRPTC model,MSDBO can obtain more optimal flight trajectories,significantly improving the efficiency of flight rerouting.Furthermore,as the thunderstorm safety threshold and turbulence coefficient threshold decrease,the total rerouting distance tends to increase.
