区域配送中心物流调度模型

针对物流系统调度中存在的区域配送"少批量,多批次"供货要求的问题,作者用时间片规范订单,通过拆分、组合订单及优化调度计划,降低成本.以某企业工程实践为背景,提出了一类区域配送的物流调度模型.该物流调度模型运用组合优化的思想,基于中央配送中心、区域配送中心、门店形成的三级运输配送体系结构,提出了在一定的约束条件(时间约束条件和空间约束条件)下,以最小成本实现物流调度计划的方法.求解算例表明,该模型对解决多货品、多门店的供货问题是有效的.

Logistics Scheduling Modle of Region Distribution Center

In order to solve the scheduling problem of frequent distribution of a little goods in one batch between regions in logistics system, We use time slices to manage orders, thus disassembling, combining orders and optimizing the planning to cut the cost. A product-scheduling model in region distribution is presented based on the retailing chain system. A method is presented which spends little cost on logistics plans under constraint conditions (time constraint conditions and space constraint conditions) by using combination and optimizing based on the three layers framework of distribution center, region distribution center and retail shop. The simulation result shows that the model and algorithm is indeed effective to solve the supply problems in multicommodity or multi-shop.
