摘　　要：基于自然灾害调研数据和救灾物流理论,对正常条件下救灾物资储备库的选址和物资配置进行了定量化研究,建立了一个具有服务质量保障约束的两阶段随机规划模型,在不确定性环境下考虑了物资的数量和运送的距离,引入参数α和Dk并进行灵敏度分析。研究结果表明,最优解受到参数α和Dk的影响,二者相同的变化未必会带来最优解相同的变化。可信度α提高时,相应的决策为选择容量大的仓库并存满,或提高存储中心的数目;而单位物资运输距离Dk降低时,只需采取提高存储中心的数目来保障服务质量约束。Based on the survey data of natural disasters and relief logistics theory, the site selection and material allocation of relief material storage under normal conditions are quantitatively studied, and a two-stage stochastic programming model with service quality assurance constraints is established. Considering the quantity of materials and the distance of transportation under uncertain environment, two parameters [α] and [Dk]are introduced and sensitivity analysis is performed. The research results show that the optimal solution is affected by the two parameters, and the same change of the two may not necessarily bring about the same change of the optimal solution. When the credibility [α] increases, the corresponding decision is to select large-capacity warehouses and make them in full storage or increase the number of storage centers;When the unit material transportation distance[Dk]decreases, we should only increase the number of storage centers to ensure service quality constraints.
