摘　　要：基于地铁轨道施工物料运输方法,通过分析受限空间特点、物料时空占用特点和物流组织难点,构建物料运输时长数学模型,提出物流组织优化方法。采用遗传算法求解对比优化前后运输时长,结果表明,优化后的物流组织模式可以减少运输时间19%。Based on the material transportation method of subway track construction,by analyzing the characteristics of confined space,the characteristics of material time-space occupation and the difficulties of logistics organization,the mathematical model of material transportation time is constructed,and the optimization method of logistics organization is proposed.The genetic algorithm was used to compare the transportation time before and after optimization.The results showed that the optimized logistics organization model could reduce the transportation time by 19%.
