7.3 Summary
• When skus are stored as full pallets in a fast-pick area then each sku is either:
– not in the fast-pick area at all; or
– is in at its minimum allowable amount; or else
– every pallet of that sku is in the fast-pick area.
• Any request for a fraction of a pallet exceeding
(savings per pick from forward area)/(cost of replenishing a pallet to the forward area)
is cheaper to fill from the pallet reserve area.
The approach to slotting presented here is a simplification of that developed in [40].
