¿How does the operator of the same rack take units for different orders?
For example: for rack 1, take 2 units of order 1, 3 of order 2 and 5 of order 3, in total rack1: 10 units.
For Rack 2, take 7 units of order1, 1 of order 2 and 5 of order 3, in total Rack 2: 13 units, the above successively until ending in rack 5, This means a pick-up order entirely by the operator.
I attach the scale model, Thank you very much for the help¡¡
