| 摘 要： | 为了设计能够最大限度地抵御自然灾害破坏并满足应急物资和抢险救援需求的物流网络,从系统可靠性角度出发,提出了区域路网应急连通可靠性的概念.运用双层规划方法构建了网络设计模型,上层模型为物流运行总时间最小和系统应急连通可靠性最大的双目标规划模型,下层模型为固定需求用户平衡配流模型.将双目标函数转化为单目标函数后求解上层模型,用改进模拟退火优化算法求解整个双层规划模型.结果表明:在相同投资约束下,上层模型中增加系统应急连通可靠性最大的目标函数后,网络最大关键度由821.55降至32.66,物流总代价降低了0.22％,物流运行时间不变.实际网络最优方案的设计应综合考虑物流效率与系统可靠性.

| Abstract: | A bi-level programming model for network design of regional emergency logistics was formulated for the network to survive in natural disasters and to meet the needs of emergency supplies.There are two objectives in the upper programming model: a shortest total logistics time and maximum connectivity reliability under emergency.The upper model was solved by transforming it into a single objective model.The lower model was a user equilibrium assignment model with a fixed demand.An improved simulated annealing... |
