基于改进集合覆盖模型的应急物流设施选址研究

Research on location of emergency logistics facilities based on improved ensemble coverage model

应急设施选址的合理性有利于高效开展应急服务,从而降低突发事件带来的危害和损失。在近几年国内外学者对应急设施选址问题的研究基础上,以最小化建设成本为目标,在满足不同风险等级需求点时间满意度约束下,建立基于应急需求点时间满意度的集合覆盖模型,并对应急物流选址未来的研究方向进行了展望。

The rationality of the location of emergency facilities is conducive to the efficient implementation of emergency services,so as to reduce the harm and loss caused by emergencies.This paper describes the research basis of covering site selection of emergency facilities by domestic and foreign scholars in recent years.In order to minimize the construction cost,a set coverage model based on the time satisfaction of emergency demand points was established under the constraints of satisfying different risk levels of demand points.Finally,the future research direction of emergency logistics site selection is prospected.
