Coronavirus disease 2019(COVID-19) has brought great disasters to humanity, and its influence continues to intensify. In response to the public health emergencies, prompt relief supplies are key to reduce the damage. This paper presents a method of emergency medical logistics to quick response to emergency epidemics. The methodology includes two recursive mechanisms: (1) the time-varying forecasting of medical relief demand according to a modified susceptible-exposed-infected- Asymptomatic- recovered (SEIAR) epidemic diffusion model, (2) the relief supplies distribution based on a multi-objective dynamic stochastic programming model. Specially, the distribution model addresses a hypothetical network of emergency medical logistics with considering emergency medical reserve centers (EMRCs), epidemic areas and e-commerce warehousing centers as the rescue points. Numerical studies are conducted. The results show that with the cooperation of different epidemic areas and e-commerce warehousing centers, the total cost is 6% lower than without considering cooperation of different epidemic areas, and 9.7% lower than without considering cooperation of e-commerce warehousing centers. Particularly, the total cost is 20% lower than without considering any cooperation. This study demonstrates the importance of cooperation in epidemic prevention, and provides the government with a new idea of emergency relief supplies dispatching, that the rescue efficiency can be improved by mutual rescue between epidemic areas in public health emergency.

突发公共卫生事件多疫区应急医疗后勤方法论[J].

2019冠状病毒病(COVID-19)给人类带来了巨大灾难,其影响还在不断加剧。应对突发公共卫生事件,及时提供救援物资是减少损失的关键。本文提出了一种应急医疗物流快速应对突发流行病的方法。该方法包括两个递归机制:(1)根据修改后的易感-暴露-感染-无症状-康复(SEIAR)流行扩散模型对医疗救援需求的时变预测,(2)基于多变量分布的救援物资分布。 -目标动态随机规划模型。特别地,分配模型解决了一个假设的紧急医疗后勤网络,考虑了紧急医疗储备中心 (EMRC),疫区和电商仓储中心作为救援点。进行了数值研究。结果表明,不同疫区与电商仓储中心合作,总成本比不考虑不同疫区合作低6%,比不考虑电商仓储中心合作低9.7%。特别是,总成本比不考虑任何合作低20%。本研究论证了防疫合作的重要性,为政府应急救援物资调配提供了新思路,即在突发公共卫生事件中,疫区间相互救援可以提高救援效率。结果表明,不同疫区与电商仓储中心合作,总成本比不考虑不同疫区合作低6%,比不考虑电商仓储中心合作低9.7%。特别是,总成本比不考虑任何合作低20%。本研究论证了防疫合作的重要性,为政府应急救援物资调配提供了新思路,即在突发公共卫生事件中,疫区间相互救援可以提高救援效率。结果表明,不同疫区与电商仓储中心合作,总成本比不考虑不同疫区合作低6%,比不考虑电商仓储中心合作低9.7%。特别是,总成本比不考虑任何合作低20%。本研究论证了防疫合作的重要性,为政府应急救援物资调配提供了新思路,即在突发公共卫生事件中,疫区间相互救援可以提高救援效率。比不考虑合作电商仓储中心低7%。特别是,总成本比不考虑任何合作低20%。本研究论证了防疫合作的重要性,为政府应急救援物资调配提供了新思路,即在突发公共卫生事件中,疫区间相互救援可以提高救援效率。比不考虑合作电商仓储中心低7%。特别是,总成本比不考虑任何合作低20%。本研究论证了防疫合作的重要性,为政府应急救援物资调配提供了新思路,即在突发公共卫生事件中,疫区间相互救援可以提高救援效率。
