摘　　要：针对震后两级救灾动态网络系统、多品种救灾物资、供不应求、多运输方式以及物资需求急迫性程度不同等特点,建立一个上层以物资运送时间满意度最大为目标,下层以物资分配公平性最大为目标的双层规划动态模型,同时考虑时间窗限制以及物资最低满足率限制、中转设施数量限制、中转设施逐渐增加、运力限制以及物资量守恒等一系列约束条件。并根据模型特点设计了一种混合遗传算法。最后,以汶川大地震应急物资配送为背景,构建两阶段算例验证了模型和算法的有效性和可行性。For the integrated optimization of transfer facility location and joint transportation, we develp an optimization model for transfer facility location and joint transportation problem, considering a series of characters such as two-echelon relief distribution network, multi-relief material, demand over supply, multi-transportation mode, different urgency with different relief, dynamic of supply and demand. The objective is to maximize the time-satisfaction of the delivery time of relief materials in the upper level and the fairness in the lower level. A set of constraints such as materials flow conservation, transit facilities limitation, capcity limitation of transit facilities, capacity constraints of different transportation mode, time constrants, lowest rate limitation, are constructted. A hybrid genetic algorithm with heuristic rules and a two-phase decoded operation is develped to solve the model. The validity of the model and algorithm are demonstrated by a numerical example based on Wenchuan earthquake relief distribution. The results show that the proposed genetic algorithm works well.
