The consumption time of a material channel is determined by the time between the reorder point and the replenishment of a material channel. This means that whenever a box is pulled out that triggers a reorder, a timer is started, and this timer finishes when that reorder is fulfilled,and the channel is replenished - regardless of any consumption events in between.
Once a reorder is triggered through the E-Kanban system, e.g., at 12:00 pm and the number of boxes arrives at the channel at 04:00 pm, then the calculated replenishment time is 4 hours. Any consumption event that occurs between 12:00 - 4:00, does not have an impact on the calculation of the replenishment time.
The average replenishment time is calculated by taking all replenishment events of the last 4 weeks, without the excluded data points based on the configuration, and averaging the time of these events. You will learn about data point exclusion in the chapter Configuration.
The standard deviation of the replenishment time is calculated by taking all replenishment events of the last 4 weeks, without the excluded data points based on the configuration, and calculating the standard deviation of the time of these events.
Calculated replenishment times, the average and standard deviation are important statistical measures which are also displayed in the charts. You can learn more about charts in the chapter “Data Visualization”.
