基于AnyLogic的进港航空器绕滑决策仿真研究

Simulation Research on Arriving Aircraft “Slide-Around” Decision Based on AnyLogic

为了提高机场的场面运行安全,降低航班跑道侵入风险,针对近距平行跑道设置了新型滑行道——绕行滑行道,探讨不同绕滑决策带来的影响与效益。以浦东机场场面布局为研究对象,对绕滑的设计和运行模式进行了分析,建立了量化绕滑效益的数学模型。以AnyLogic为仿真平台构建了离散事件随机仿真模型,主要包括决策模块和优先级模块,模拟了航班到港和离港间隔时间方案不同情况下的3种绕滑决策对进离港航班的全局滑行时间和油耗量的影响,仿真结果表明,绕滑产生了一定程度的优化效果,尤其是在航班离港高峰期,进港航班全部选择绕滑使全局滑行时间和平均油耗量分别减少了37.1%和21.5%。

In order to improve the safety of airport surface operations and reduce the risk of runway incursion of flights,a new type of taxiway,the-around-taxiways,was designed for the parallel runways in close proximity to explore the impacts and benefits brought by different decisions of the around taxiway.Taking the field layout of Pudong Airport as the research object,firstly this research analyzed the design and operation mode of Slide-Around,and established a mathematical model to quantify the benefits of Slide-Around.Secondly,AnyLogic was used as the simulation platform to construct a discrete-event stochastic simulation model,which mainly included a decision module and a priority module,to simulate the effects of three Slip-Around decisions on the global taxiing time and fuel consumption of arriving and departing flights in different cases of intervals scenarios,and the simulation results showed that Slide-Around produced some degree of optimization,and especially in the peak period of flights′departing,the arriving flights all chose slip-around to make the global taxiing time and fuel consumption,Slide-Around can reduce the global taxiing time and average fuel consumption by 37.1%and 21.5%.
