    摘要:

    突发事件救援的紧迫性凸显了及时、合理地向灾区分发应急物资的重要性,应急物资配送中心车辆的调度方案成为应急物流的关键。该研究考虑在交通路网行程时间不确定的情况下,以车辆调度方案的最大后悔值(鲁棒成本)最小化为目标,建立应急救援车辆调度优化模型,并设计Benders分解算法来求解该模型。该算法先将模型分解为主模型和子模型,再加入Benders最优割约束,不断迭代,直到得到最优解。研究结果表明:该模型能以最小的鲁棒成本实现应急物资配送中心车辆的合理调度,满足车辆最大救援时限、受灾点需求优先级等要求。与其他模型相比,该模型得到的车辆行程安排更合理。该研究可为应急物流决策方案提供参考。

    Abstract:

    In the event of an emergency, due to the urgency of rescue, it was very important to distribute emergency supplies to the disaster area in a timely and reasonable manner. Therefore, the decision-making of the vehicle dispatching scheme of multiple emergency supplies distribution centers became the key link of emergency logistics. Considering the uncertain travel time of the traffic network, to minimize the maximum regret value (robust cost) of the vehicle scheduling scheme, an optimization model for emergency rescue vehicle scheduling was established. Benders decomposition algorithm was designed to solve the model. First, the model was decomposed to obtain the main model and sub-model, and then the Benders optimal cut constraint was added to the solution for continuous iteration. The result of the example shows that the research model can achieve the reasonable scheduling of vehicles in multiple emergency material distribution centers with the minimum robust cost, meet the requirements of the maximum rescue time limit of vehicles, the priority of the demand of the disaster site. The vehicle travel time obtained from this model is more reasonable. This study can provide a reference for emergency logistics decision-making plans.
