针对突发公共卫生事件应急管理体系中应急物资需求的不确定性和连续性以及应急救援是一个同时在多疫区间展开的多周期救援过程这一实际,提出了多疫区多周期应急物资协同优化调度方案.首先在分析传染病扩散规律的基础上,结合传染病潜伏期的不确定性所引起的应急救援的时滞性,采用纵向配送和横向转运相结合的协同配送模式,构建了一类应急物流网络优化多目标随机规划模型;其次采用遗传算法给出了该优化模型的求解算法;最后通过仿真算例验证了模型及算法的有效性和可行性.
In response to the uncertainty and continuity of emergency supplies in emergency management system of emergency public health emergencies and the fact that emergency rescue is a multi-period rescue process that is carried out simultaneously in multiple epidemic intervals, multi-cycle emergency supplies coordination Optimization scheduling scheme.Firstly, on the basis of analyzing the law of spread of infectious diseases and combining with the time delay of emergency rescue caused by the uncertainty of latent period of infectious diseases, a collaborative delivery model based on vertical distribution and horizontal transportation is constructed. The emergency logistics network is used to optimize the multi-objective stochastic programming model. Secondly, the genetic algorithm is used to solve the optimization model. Finally, the simulation results show the effectiveness and feasibility of the model and the algorithm.
