摘　　要：研究应急物资配送中的两级车辆路径决策策略与应急物资配送绩效问题.首先以最后完成任务的最小时间为目标,建立了两级车辆路径模型;然后针对主仓库恢复配送时间不确定性问题,提出了4种应对策略:独立策略、乐观协同策略、悲观协同策略和折中协同策略,设计了多起点迭代局部搜索算法和仿真程序;最后通过数值算例比较了4种策略对应急物资配送绩效的影响,比较结果表明,折衷协同策略的表现效果最好.The two echelon vehicle route decision strategies and the performance in rescue resource distribution system are analyzed. Firstly, a min-max two echelon vehicle routing model is developed. Then, for the main warehouse delay time uncertainty, four decision strategies are proposed, which are simple strategy, optimistic collaboration strategy, pessimistic collaboration strategy and mixed collaboration strategy. A multi-star iteration local research algorithm and simulation program are developed. Finally, numerical studies are presented to compare the impact of decision strategies on the relief performance, and the results show that mixed collaboration strategy is the best strategy in four strategies.
