Optimization of Emergency Material Dispatch Scheme Considering Flood Submergence

本文研究了洪灾背景下考虑洪水淹没的应急物资调运优化问题，目标是在车辆和道路受限的情况下，将低海拔地区的应急物资快速转移到高海拔仓库。论文提出了两种求解方法：遗传算法和一种分阶段的混合算法(近似解法)，并通过一个25个物资储备库的算例进行了对比分析，得出混合算法在求解效率和结果优越性方面更具优势的结论。This paper investigates the optimization problem of emergency material transportation considering flood inundation in the context of flood disasters. The objective is to quickly transfer emergency supplies from low-altitude areas to high-altitude warehouses under the constraints of limited vehicles and road access. The paper proposes two solution methods: a genetic algorithm and a phased hybrid algorithm (an approximate solution method). Through a comparative analysis using a case study of 25 material reserve depots, it concludes that the hybrid algorithm has advantages in both solution efficiency and result superiority.
