基于冲突点避让机制选择的航空器滑行路径优化

针对航空器地面滑行的问题,提出了冲突点选择避让机制来优化航空器滑行路径。通过构建地面滑行路径的节点-路段模型,以航空器全部滑行到预定节点所用时间最短为目标,建立了路径滑行优化模型。通过建立可行路径集,利用启发式搜索算法,从静态路径规划、动态路径规划两阶段对滑行路线进行优化,得到航空器滑行优化路径。以某机场某一时段内航班到离港时间数据为例,对算法进行了验证,结果显示:经算法优化后,可减少时间段内各航班的最短滑行路径的冲突,缩短滑行时间,滑行道使用较分散,可降低航空器滑行中运行风险。

Optimization of Aircrafts Taxiing Bath Based on the Choice of Conflict Point Avoidance Mechanism

In view of the problem of aircrafts ground taxiing, a conflict point selection mechanism is proposes in the paper to optimize the route of aircrafts taxing. By constructing the node path model of the ground taxi path and taking the shortest time that all the aircrafst skate to the predetermined node, the path taxiing optimization model is established. By establishing feasible path set, the heuristic search algorithm is used to optimize the taxi route from the two stages of static path planning and dynamic path planning, and get the optimal path of aircrafts glide. In a certain period of time, the algorithm is verified through the airport flight departure time data. The results showed that the optimized algorithm can reduce taxiing conflict, shorten the taxi time, scatter taxiway and reduce the operation risk of the aircrafts.
