【摘要】 在总结确定型配送/收集行车路线模型和嵌套策略模型的基础上,就一对多物流网络,针对客户同时有配货和退货需求的两类配退货系统,分别建立了嵌套策略成本优化模型,并以某啤酒厂配送啤酒和收集啤酒瓶的数据进行了实证分析,通过对各种影响因素的敏感性分析,揭示了配退货系统物流成本的一些规律。更多还原

【Abstract】 On the basis of summarizing the ascertained model of vehicle routing problem with pickups and deliveries and the model of nested sequence policy,two kinds of pickup and delivery systems under the one-to-many logistic network were considered,and cost optimization models for nested sequence policy were set up respectively.According to the data of delivery of beer and collection of beer bottles in one beer factory,a positive analysis was carried out.Through the sensitive analysis of different factors,some laws of logistic costs of pickup and delivery system were revealed.更多还原
