摘　　要：提出了一套应急情况下机场跑道的自动化抢修方案推算流程。一方面结合元胞自动机技术,对抢修全过程进行精细化模拟,精准掌握抢修过程中各个时刻机场跑道的抢修进度和保障能力;另一方面提出了改进的Dijkstra算法,在通行速度动态变化的路网上快速获取一条耗时最短的路径,从而支撑机场跑道抢修物资的全局调度。实验结果表明,该机场跑道抢修方案推算流程能够在较短时间内分析获得准确的抢修方案,有效支撑应急情况下的保障需求,为应急抢修提供辅助决策支撑。This research proposes a set of automatic repair scheme for airport runway emergency repairing progress.On the one hand,the process combines cellular automata technology to carry out fine simulation of the whole process of emergency repair,so as to accurately grasp the emergency repair progress and support capacity of the airport runway at each time during the emergency repair process.On the other hand,an improved Dijkstra algorithm is proposed to quickly obtain the shortest and time-consuming path on the road network with dynamic traffic speed,thus supporting the global scheduling of airport runway repair materials.The experimental results show that the calculation process of the airport runway emergency repair plan can analyze and obtain an accurate emergency repair plan in a short time,effectively support the security needs in emergency situations,and provide auxiliary decision-making support for emergency repair.
