本研究主要探讨工厂内牛奶运送系统中的物料流，其中一辆拖车列车将物料从一个仓库运送到多个工作站。本文的重点是处理列车容量的问题，由于工作站的需求，几个独特的产品模型需要独特的需求要求组装的动态性质。动态列车周期时间、早期装载和最大限度地减少拖车的额外数量是本研究中使用的工具，以最大限度地减少所需的列车容量，使车站附近的区域不会因垃圾箱超过其容量而拥挤。这是使用四个整数规划模型逐步完成的。随机生成的实例表明，结合这三个工具的结果大大减少了额外需要的拖车的数量，但在拖车的最大需要的数量略有减少。
This study investigates material flow in in-plant milk run system in which a tugger train transports materials and parts from a warehouse to several workstations in one route. The focus of the paper is to deal with train capacity problems due to the dynamic nature of workstations demand where several unique product models needing unique demand requirements are assembled. Dynamic train cycle time, early loading, and minimising extra number of trailers are the tools used in this study to minimise the needed train capacity keeping the area beside stations not to be crowded with bins more than its capacity. This is done step by step using four integer programming models. Randomly generated instances showed that combining the three tools results in great decrease for the extra needed number of trailers, but small decrease in the maximum needed number of trailers.
