Put-away for addressed system and without

Suppose we need to put four boxes into storage area where no addressing exists. Boxes containing A,B,C and D product should be put into storage area so they could be found and picked. So they are put in an alphabetical way. For four different boxes four phases of movement should be done. Phase (A) is the starting point. On phase (B) 10 boxes should be moved so box with product A could be put into the shelve. On phase (C), 7 boxes should be moved in order to open place for product D. On phase (D), 5 boxes should be moved in order to open place for product F. On phase (E), 2 boxes should be moved. 22 movements made to place 4 different products.


For a system having addressing system only four movements are done. Those movements are placing four different products to the empty shelves at the end.



The put-away and inbound processes for a system without addressing system costs at least 40% more than the same operations on an addressed system. No need to mention manpower allocated and time spent comparisions. Also for a system without addressing system operational space is bigger than ordinary addressed sytem. Quantity of product stored per m2 is less than ordinary sistem with addressing because no mix containers could be created and per every product range there should be extra space for put-away.

The picking processes are slower for systems without addresses and picking success rate is less than ordinary systems. I will cover picking issues in more details.
