A-SMGCS航空器动态最优滑行路径规划研究

机场场面航空器的动态最优滑行路径研究是A-SMGCS的前提和关键,包括动态路径规划和滑行时间调度两方面.针对A-SMGCS中动态路径规划的复杂性和实时性,依据跑道、滑行道和停机坪的拓扑结构及管制规定建立了基于Petri网的场面活动模型及相关约束规范.根据该模型及约束规范,并将静态预选路径作为可行解集,推导出场面各个时刻的机场状态,并从中选取最优路径.仿真实例表明动态路径规划可以最大限度避免滑行冲突,减少航空器的等待时间,显著提高场面运行效率.

Research on the Optimization of Aircraft Dynamic Routes Planning for A-SMGCS

Aircraft dynamic routes planning on the airfield surface is the precondition and critical part of the A-SMGCS, which including the dynamic routes planning and taxing time distribution. Due to the complexity and real-time demanding of dynamic routes planning in A-SMGCS, this paper established a surface movement model based on Petri-Net, according to the structure of airfield surface and ICAO- 9830. With this model and constraint rulers, using the planned static routes as the initialization routes, the optimized path can be derived from the Petri-Net state in every time-step period. The re- sult of simulating indicates that dynamic taxiway routes planning can decrease the potential conflic- tions obviously, reducing holding time of aircrafts and improving the efficiency of airport.
