基于最小封控时间的机场跑道毁伤评估方法

Airport Runway Damage Assessment Method Based on Minimum Blocking Time

以打击后的机场跑道为背景,解决对敌方机场毁伤评估问题,建立最小封控时间窗口搜索模型以及基于封控时间构建跑道毁伤评估标准,利用改进的免疫遗传算法求解模型。考虑到遗传算法盲目性和只能求解近似解的特点,引入免疫过程并增加记忆单元,解决过早收敛和近似最优解问题。通过仿真对比,所提出的算法能够有效搜索跑道的最小封控时间窗口,支撑评估机场毁伤程度,通过改进免疫遗传算法,有效提升搜索效率的同时避免陷入局部解,并求解真正的最优解。

Based on the background of airport runway after strike,the problem of damage assessment of enemy airport is solved.The search model of minimum blocking time window is established,and the runway damage evaluation criteria is constructed based on blocking time.The model is solved by improved immune genetic algorithm.Considering the blindness of genetic algorithm and the haracteristics of only approximate solution,the immune process are introduced and the memory unit is added to solve the problem of premature convergence and approximate optimal solution.Through simulation and comparison,the algorithm proposed in this paper can effectively search the minimum blocking time window of the runway,and can support the evaluation of the airport damage degree,the search efficiency is effectively improved by improving the immune genetic algorithm,the falling into the local solution is avoided,and the real optimal solution is solved.
