基于DEDS的A-SMGCS航空器动态滑行路径规划

为实现先进场面引导与控制系统中航空器动态滑行路径规划，建立了基于静态路径规划、动态路径规划和实时路径更新的总体框架。依据跑道、滑行道和停机坪使用规则建立基于Petri网的场面活动模型及线性不等式约束的活动控制规范，给出了当前规划航空器在满足与场面其他滑行航空器不冲突条件下的极大代数状态方程，并将静态预选路径作为可行解对滑行路径进行动态优化。针对滑行中出现的时间偏差，采用时间窗调整或再规划策略更新路径。仿真实例结果表明,动态路径规划从战术上避免滑行冲突，减少航空器的等待时间，显著提高了场面交通容量。

Aircraft dynamic taxiway routes planning for A-SMGCS based on DEDS

To implement dynamic taxiway routes planning for aircrafts in an advanced surface movement guidance and control system (A-SMGCS), the general framework including static planning, dynamic planning and on-line updating taxiway routes is built. The surface movement model based on Petri nets and the surface movement controlling regulations based on linear inequalities are proposed according to runway, taxiways and apron running regulations. The max plus algebra state equation for the current planning aircraft which does not clash with other surface aircrafts is proposed, and the dynamic taxiway is optimized from static pre-elected shortest routings. If time variation occurs during taxiing, time window adjusting or routes re-planning is used to update taxiway routes. The simulation result indicates that dynamic taxiway routes planning decreases the potential conflictions tactically, reduces the holding time of aircrafts and improves the capacity of airports.
