摘　　要：为解决灾后应急物资供应问题,针对运输的紧迫性和逐级调配的现实模式,采用货车-飞机-货车联合运输的方式,结合由物资供应点-中转点-分配中心-需求点构成的4级服务网络,从政府、受灾者和救援人员3方的角度,建立以最小化系统总运营成本、总运输时间和运输车辆驾驶员心理成本为目标的多目标混合整数动态规划模型,并采用Epsilon约束算法求解模型,分析关键参数的灵敏度,结合案例计算验证模型运算效率。结果表明:该模型能够得到一组有效的非支配解,即Pareto前沿,提供不同决策侧重点的多阶段物资调配方案;中转物资单位操作时间过长或过短都会导致救援总时间增加;系统总成本不会随着驾驶员心理极限运输时长的改变单调变化。In order to solve the problem of post-disaster emergency material supply,this paper was targeted at the multi-modal transport mode of truck-aircraft-truck,and the four-layer emergency service network consisting of"material suppliers,transfer stations,distribution center,and demand points"in view of the urgency of emergency needs and the layer-by-layer transportation mode in real logistics operation.A multi-objective mixed integer dynamic program was established with the objectives of minimizing total system operational cost,total transportation time and truck drivers'psychological cost from the perspective of the government,disaster victims and drivers involved in emergency transportation,respectively.The Epsilon constraint algorithm was adopted to solve the model,and a sensitivity analysis was given to test the performance of some key parameters.The results of the case study show that the model can obtain a set of effective nondominated solutions,i.e.,Pareto frontier,which can provide helpful multi-stage emergency supply plans with different decision preferences.A longer or shorter operation time in the transfer stations will increase the total emergency response time.The total cost of the system will not move monotonously with the change in the driver's psychological limit driving time.
