摘要

为提升高高原机场应急救援效率,对高高原机场应急资源配置进行优化研究.分析高高原机场应急救援的特殊性,细分高高原机场应急救援作业流程.基于赋时Petri网对高高原机场突发事件应急救援作业的离散事件动态系统进行建模,分析模型可靠性,基于库所不变量分析法求解关键路径.实验以高高原机场航空器冲偏出跑道为例进行算例分析,求解关键路径,并对关键路径作业进行资源调整,实现应急救援作业周期优化.%In order to improve the emergency rescue efficiency in super-high plateau airports, this paper optimizes the emergency resources allocation in super-high plateau airports. Firstly, the operation characters of super-high plateau airport emergency rescue was analyzed, and the sub-operations of super-high plateau airport emergency rescue were obtained. Then, the emergency rescue dynamic system was modeled based on the timed Petri net, and the model reliability was analyzed. The critical path was solved based on the invariant analysis method of the place. Experiments were based on a case of aircraft rushing out of the runway. The critical path is solved, and the resource adjustment of the critical path operation is carried out to realize the optimization operation cycle. Finally, the resource adjustment of the critical path operation was carried out to optimize the operation cycle.
