Identifying locations in the Warehouse
If you want to computerize your warehouse you need to identify storage locations within the Warehouse. Usually you label every possible storage location with a 3D coordinate.
Then every location can have it’s unique ID consisting of Row of shelfes (red in the image above), Column (all locations above each other; blue in the image above) and Level (all location besides each other; yellow in the image above).
This scheme allows you to label allocations with Row-Column-Level, e.g. 01-02-03 for the first Row, second Column, third Level. Usually labels identifying the storage locations are places on the shelfing above level 1.
