【摘要】 针对应急物流基站的规划建设问题,提出基于能量均衡的方法对问题进行优化研究,以实现最小的物流基站数量满足最大的应急物流需求。合理的设置应急物流基站,可以为突发物流需求提供最快速的配送,首先通过集合覆盖模型来确定网络覆盖最大化的应急物流基站数量,然后基于能量均衡的方法来确定这些基站的位置分布,以达到最优化的应急物流基站选址。通过仿真实验进行验证和讨论,本研究方法可以在最小基站数量设置的情况下满足最大区域的物流网络覆盖需求,在突发事件后,15分钟内物资可以配送到网络中的任何地方,实现了时间最小化和覆盖最大化的目标。更多还原

【Abstract】 In this paper,in view of the programming and planning of emergency logistics stations,we proposed the method based on energy equilibrium to realize maximum coverage to satisfy maximum emergency logistics demand using minimum logistics stations.First,we used the set coverage model to determine the number of stations needed to ensure maximum network coverage,then used the energy equilibrium based method to determine the locational distribution of them.Then in a simulation experiment,we demonstrated that the method proposed in this paper could provide maximum coverage using minimum number of stations and distribute the emergency materials to wherever they were needed within the network within 15 minutes.更多还原
