Determine the Average Number of Picks per Picking Tour
The average number of picks per tour can be determined in several ways.
A
WMS-Analysis
If a Warehouse Management System (WMS) is used, the average number of picks per tour can be taken from the WMS. The analysis varies depending on the WMS used.
B
Analysis of the Order Structure
If a pick order also corresponds to a sales order, the number of picks per order can be determined.
C
Process Observation
In a process observation, the frequency can be recorded with the help of a tally sheet or a corresponding app.
2
Determine the Average Walking or Driving Time/Distance per Picking Tour
The second step is to determine the average distance traveled.
A
Motion-Mining®
As part of a Motion-Mining® project, both the distance travelled and the time spent walking/driving per tour can be determined.
B
Step Counter
Using a smartphone or simple pedometer, the distance covered per tour can be determined.
C
Measuring the Layout
In systems where the same distance is covered in each tour (e.g. looping lanes), the distance can be measured on the layout.
3
Calculate the Distance or Travel Time per Pick Position
The average distance per pick is calculated by dividing the distance per trip by the number of picks per tour. The calculation for pick items per day and distance per day can be determined in the same way. If the time required for the tour is available, the time per pick can be calculated identically.
4
Calculate Savings Potential
Depending on the selected solution, the distance travelled can be significantly reduced. The savings potential results from the time required for the saved distance.
A
Distance Available
If only distance is available, it must be converted to time. For example, MTM values for time per meter can be used for different vehicles or aids.
B
Time Available
Once the time saved per pick is known, the number of picks per day can be extrapolated to the total number of employees.
