A regional distribution center moves 4,000 orders a day through four areas strung along one main aisle: Receiving (R), Reserve storage (S), Pick-and-pack (P), and Dispatch (D). The industrial engineer's from-to chart, in pallet-loads per day, reads: R→S 120, S→P 100, P→D 90, R→P 30, S→D 20, P→S 15 (returned totes).
