基于适应性供应链的应急物流网络优化研究

科学合理的应急物流网络是应急物流快速实现的基础,它具有很强的经济效益和社会效益。基于适应性供应链的核心理念,首先给出了适应性供应网络的概念模型,构建了应急物流网络系统,并将该系统的运行划分为日常管理、应急启动、平衡运行和善后处置四个不同阶段。然后分析了不同阶段应急物流所追求的目标重要性的变化趋势,引入罚函数系数来实现不同阶段应急物流的时效性、经济性、风险性三个目标的均衡。最后建立了应急物流网络优化模型,为保障应急物资运送的畅通性、时效性和安全性提供辅助决策方案。

A Study on Network Optimization of Emergency Logistics Based on Adaptive Supply Chain

The scientific and reasonable emergency logistics network, with strong economic and social benefits, is the foundation for emergency logistics to quickly come into effect. Based on the core philosophy of adaptive supply chain, we first give the conceptual model for adaptive supply network, and establish the emergency logistics network system,and divide its operation into four different stages which are routine management stage, emergency start-up stage,smooth operation stage aftermath handling stage. Then we analyze the change trend of significance for each objective that emergency logistics pursues in these stages, and introduce penalty function coefficients to strike a balance between emergency logistics＇ timeliness economy, risk. Finally, we build a network optimization model for emergency logistics to provide decision-making plans for the smooth, timely and secure delivery of emergency supplies.
