Extending Little’s Law to single order throughput times
本文基于利特尔法则，将平均产出时间分解为依赖于在制品和依赖于订单顺序的两个部分，从而描述单个订单的产出时间分布。
It has long been established that the mean throughput time is a result from the relationship between the work in process (WIP) and output rate. In reality, however, throughput times are frequently dispersed broadly around this mean. With the aid of a model originally developed for lateness, it is now possible to describe the throughput times of individual orders. Accordingly, the throughput time can be divided into two components: WIP-dependent throughput time and sequence-dependent throughput time.
