摘　　要：研究未定路网情景下灾后应急物资多方式配送的定位-路径问题(LRP),综合考虑应急路网连通情况、时间窗限制、车辆随机行驶时间、应急物资满载直配与巡回配送等特性,以应急物资总配送时间最短为目标,构建一个灾后应急物资多方式配送的LRP优化模型,并根据模型特点设计一种混合启发式算法予以求解。最后,通过算例验证了本文模型和算法的可行性与有效性。The location--routing problem （LRP） for multimodal deliveries of relief materials in uncertain network after natural disasters was studied. A LRP model of multimodal deliveries was developed by considering the following charac- teristics： road damage of the part logistics network, time window constraints, stochastic vehicle travel time and demand segmentation strategy employed for the node with great demand. The goal is to minimize the total time in delivering relief materials. A hybrid heuristic algorithm was proposed to solve the model. Finally, the feasibility and validity of the pro- posed approaches were demonstrated by a numerical example.
