摘　　要：Under the threat of bio-terrorism,this paper aims at improving the emergency rescue system's ability of dealing with a public health emergency.Focusing on the demand network,this research establishes the emergency rescue supply storage network under a danger diffusion environment.Combined with the infectious disease diffusion model,the traditional set covering model is rebuilt taking the decision optimization of reserve quantity into consideration.Under the premise of a certain emergency service level,the collaborative location optimizing model of an emergency rescue supply storage network is established in order to minimize the sum of the building costs and the preserving costs.The model is proved to be effective through numerical simulation.The collaborative location optimization of the nodes of the emergency rescue supply storage network and the reserve quantity of each storage node is realized.面对生物恐怖威胁,为提高应急救援系统应对突发公共卫生事件的能力,以危险源扩散环境为背景,围绕潜在的需求网络,研究构建救援物资的储备库网络.结合传染病扩散模型,对传统的集合覆盖模型进行改造,加入物资储备量决策优化,在满足一定应急服务水平的前提下,以储备网络建造成本和物资储藏成本和最低为目标,研究建立了应急物资储备库网络协同选址优化模型.并通过数值仿真验证了模型的有效性,实现了储备库网络节点选址及各储备库物资储备量的协同优化.
