摘要
对于航空器在机场滑行路径的优化问题,考虑航空器的滑行过程,建立航空器滑行运动模型,并在此基础上以滑行时间和滑行油耗作为优化目标,结合安全间隔、滑行规则和冲突避免限制规则为约束条件建立了滑行路径优化模型。采用以Dijkstra算法为基础的模型求解算法,在保证滑行道调度零冲突的前提下,减少总的滑行油耗和滑行时间。算例分析结果表明,提出的航空器滑行路径优化模型和优化方法是可行的,可为机场的场面调度提供决策支持。
In this paper,we discussed the optimization of aircraft taxiing path at the airport,the aircraft taxiing motion model was established by considering the taxiing process,and we based on this,put the taxiing time and the taxing fuel consumption as the optimization targets,combined with the safety interval,taxiing rules and conflict avoidance restrictions.The rule establishes a taxi path optimization model for the constraints.The optimization of taxi path algorithm for solving model was proposed based on Dijkstra algorithm to reduce the total coasting fuel consumption and taxi time,and then we considered the premise of ensuring zero collision of taxiway scheduling.The simulation analysis results show that the aircraft taxi path optimization model and optimization method are feasible,it can provide decision support for the surface scheduling of the airport through aircraft motion process.
