车间内多周期混合收送货物流调度优化研究

Research on Optimization of Multicycle Logistics Scheduling Problem with Pickup and Delivery in Assembly Plant

从精益物流角度出发,生产车间的停线待料、成品堆积、车辆堵塞等增加了生产线成本,传统的收货与送货存在严重的资源浪费。在混合收送货的基础上重点研究了循环供料及周期间的关系,建立了装配车间考虑时间窗的多周期混合收送货物流调度模型,并以S公司电动工具装配车间为例,分别用单周期优化模型和多周期物流调度优化模型求解,利用Lingo编程计算给出具体调度方案,将两种方案进行对比,结果表明多周期调度方案更优,可进一步降低装配车间的成本。

Starting from the perspective of lean logistics,stop for materials,finished products stock,vehicle congestion and other problems in assembly plant increase the production cost,and the serious waste of resources exists in traditional goods delivery.This paper tries to focus on the relationship between cycle feed and the cycles.Besides,multi-cycle logistics scheduling model with pickup and delivery in which time window was taken into account was established.The power tools assembly plant of S Company was taken for example.The single cycle optimization model and multicycle logistics scheduling optimization model were used to solve the problem,and the specific scheduling scheme was provided by Lingo programming.The two schemes were compared.The results show that the multicycle optimization model is much better than the single one,because it can further reduce the cost.
