摘要: 为实现防汛应急物资多层级储备库的协同布局和储备分配,综合考虑不同等级洪涝灾害的物资需求差异、多物资选址分配策略、多层级出救规则和企业代储点等因素,构建最小化加权总运输时间和系统总成本的储备库公私协同选址-分配模型;设计一个加入多个全局变量的改进非支配排序遗传算法(NSGA-II)对模型进行求解;求解出武汉市各层级储备库选址、储备量和分配关系的最优解集,并对比有无代储点对目标函数带来的影响。结果表明:选址-分配模型能够实现防汛应急物资储备的综合决策,在选择代储点时,物资满足率较为均匀,能避免某种物资出现极度短缺,且能减少时间、降低成本。

Abstract: In order to achieve collaborative planning, reserve and allocation for multi-tiered repositories of flood emergency supplies, a public-private collaborative LAP model with minimum weighted transit time and system cost was established with consideration of factors such as differences of supply demand for different levels of flood disasters, multi-supply location-allocation strategies, multi-tiered rescue rules and commercial storage spots. Then, an improved NSGA-II with multiple global variables was designed to solve the model. Finally, with Wuhan city taken as an example, analysis was made to find optimal solution of location, supply reserve and allocation relation for repositories at various levels, and influence of presence or absence of storage spots on objective function was compared. The result shows that the LAP model can realize comprehensive decision-making for flood emergency supplies reserve. In selection of storage spots, supply satisfaction rate is relatively uniform, thus avoiding extreme shortage of some supplies and simultaneously reducing time and cost.

Key words: flood emergency logistics, location-allocation problem (LAP), public-private collaboration, commercial storage spot, non-dominated sorting genetic algorithm (NSGA-II)
