Unit loads are combinations of individual items which are moved by handling systems, usually employing a pallet of normed dimensions.[18]
Handling systems include: trans-pallet handlers, counterweight handler, retractable mast handler, bilateral handlers, trilateral handlers, AGV and stacker handlers. Storage systems include: pile stocking, cell racks (either static or movable), cantilever racks and gravity racks.[19]
Order processing is a sequential process involving: processing withdrawal list, picking (selective removal of items from loading units), sorting (assembling items based on destination), package formation (weighting, labeling and packing), order consolidation (gathering packages into loading units for transportation, control and bill of lading).[20]
Picking can be both manual or automated. Manual picking can be both man to goods, i.e. operator using a cart or conveyor belt, or goods to man, i.e. the operator benefiting from the presence of a mini-load ASRS, vertical or horizontal carousel or from an Automatic Vertical Storage System (AVSS). Automatic picking is done either with dispensers or depalletizing robots.
Sorting can be done manually through carts or conveyor belts, or automatically through sorters.
