| 摘 要： | 为了增强越库配送对市场随机需求的适应性,兼顾总体利益和零售商门店的个体利益,充分考虑随机需求、库存、配货和原始订单等因素,以提高最终订单满足随机需求的置信水平、增加配送车辆满载率和降低总运营成本为目标,建立了多目标随机规划模型,构建了正规化的多目标适应度函数,设计了具有自适应特点的遗传算法,并进行了实例研究.结果表明:与原始订单相比,最终订单满足随机需求的置信水平、配送车辆满载率分别增加了3.59%、12.71%,每天的总成本平均减少了631 845元,降低了13.73%.

| Abstract: | In order to enhance the adaptivity of cross-docking logistics(CDL) to stochastic market demand,a multi-objective stochastic programming model was established.Taking both local and global interests into account and considering the factors such as random demand,inventory,distribution,and original orders,This model aims at improving the confidence level of final orders to meet the stochastic demand,increasing the vehicle loading rate,and reducing the total operation cost,and To solve the model,a multi-objectiv... |
