面向正点率提升的华北机场群航班时刻优化

近年来,区域机场群协同发展逐渐成为了未来民航发展的基本导向。然而,相比国外关于机场群的研究水平,我国尚处于萌芽阶段,出现了机场群内发展不均衡、缺乏协同、功能定位不清晰、空管运行难度大、服务品质降低等问题。因此,以京津冀机场群为研究对象,借鉴国外先进发展经验,从协同发展的角度对机场群航线优化进行研究。构建了以提升航班正点率为目标的机场群现有航班时刻优化模型,运用粒子群迭代寻优算法求解最优解,将优化后的航班时刻表用SIMMOD进行仿真验证,实验结果表明,经航线优化后的京津冀机场群航班延误得到了缓解,且多机场群系统的航班冲突得到了明显的降低。

Research on Flight Time Optimization of North China Regional Airport Group for Improving the Accuracy of Flight Time

In recent years,the coordinated development of regional airport groups has become the future trend.However,the problems such as unbalanced development in multi-airport system,lack of coordination,unclear function,difficult management,and low service quality have emerged.Therefore,this paper takes Jing-Jin-Ji multi-airport systems as the research object,and learns the advanced development experience to study the optimization of air route in multi-airport systems from the perspective of coordinated development.The flight schedule optimization model was built to improve the on-time rate.And then,the optimal solution was obtained through the iterative particle swarm optimization algorithm.Finally,the optimized flight schedule was verified by SIMMOD.Simulation results show that the flight delays in Jing-Jin-Ji airport group have been alleviated through the flight path optimization.In addition,the flight conflicts of multi-airport system have also been significantly reduced.
