In this situation, the order picker also has to take products from 3 locations.
In this case however, after stopping on location 2, the order picker will not move his (her) pallet to pick on location 3.
As such, (s)he has made only 2 stops for 3 order lines.
(Number of order lines / Number of Stops) = 3 / 2 = 1.5
The higher this ratio, the fewer stops are necessary.
Taking that one Stop generates a loss of 5 seconds, you can save 35 worked hours by reducing 25 000 Stops.
