The consumption time of a material channel is determined by the time between the consumption of boxes. This means that whenever a container is pulled out, a timer is started, and this timer finishes when another container is pulled out of the same channel - regardless of any replenishment events in between.
A worker in the factory pulls out a container at 12:00 pm. After he finished working with the goods in the box, he pulls out another one at 04:00 pm. Hence, the calculated consumption time is 4 hours in this case. As described before, newly added boxes to the channel do not have an impact on the consumption time.
In addition to the consumption time, the application also calculates two additional KPIs related to the consumption time:
- Average of the consumption times
- Standard deviation of the consumption times
The average consumption time is calculated by taking all consumption 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 consumption time is calculated by taking all consumption 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 consumption 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”.
