The plain-words read of this example
This SKU ranks 180 of 4,000, so it is a A mover. For 3.0 days of supply it needs 62.5 ft³ (one pallet position), refilled 2.3 times a week. Today's 10.0 ft³ slot lasts 0.5 days. Move up: the slot is too small and drives extra refills. Sizing the face to the restocks it causes is the fast-pick logic in Bartholdi and Hackman.
