论文摘要
本文在随机存储的假设下，在仓库中介绍了仓库中总采摘时间的前两个时刻的精确推导。该分析是针对一般订单大小分布进行的，并根据订单大小分布的概率生成功能提供公式。这些结果用于研究路由启发式，顺序大小分布和仓库布局之间的差异。具体而言，我们将带有$ C $拾取器的仓库建模为M/g/c队列，以估计平均订单登陆时间。
This paper presents exact derivations of the first two moments of the total picking time in a warehouse for four routing heuristics, under the assumption of random storage. The analysis is done for general order size distributions and provides formulas in terms of the probability generating function of the order size distribution. These results are used to investigate differences between routing heuristics, order size distributions and warehouse layouts. In specific, we model a warehouse with $c$ pickers as an M/G/c queue to estimate the average order-lead time.
