在将类似问题总结为考虑风险阈值的物流基础设施网络布局模型（Logistics Infrastructure Network Model under the Risk Threshold: LINM-RT）的基础上，把物流网络上的设施分为两种：“不可靠物流设施”和“可靠物流设施”。模型考虑了设施的最优数量和布局方案，研究拟通过各个设施对消费者需求的配送情况和设施类型的不同给出不同设施的布局方案，分析中断风险概率和消费者的需求对布局产生的影响和表现。分析了在已知条件充足的情况下，如何将LINM-RT模型简化为经典的无设施容量限制设施布局问题模型，并用拉格朗日松弛算法快速地去求解LINM-RT模型。研究结果证明了风险阈值的存在，用算例进一步说明在不同风险概率下物流基础设施网络布局选择是不同的。

Related to the application of operations research and theoretical studies, a model of logistics infrastructure network design under risk threshold (Logistics Infrastructure Network Model under the Risk Threshold: LINM-RT) was proposed. The facilities on the logistics network were divided into two types "unreliable logistics facilities" and "reliable logistics facilities". Different facility layout plans were proposed through distribution of various facilities for consumer demand and different types of facility. The impact and performance of disruption risk probability and consumer′s demand generated on site were analyzed. How to reduce LINM-RT model to the classic non-facility capacity constraints facility problem model and use Lagrangian to solve LINM-RT model quickly were analyzed. The results prove the existence of the risk threshold. With examples, it is illustrated that options of logistics infrastructure network layout under different probabilities of risk are different.
