Spaghetti — Warehouse Pick Round
Three operators on a 60-metre chilled pick face walk 553 m over 18 legs with 36 route crossings; re-slotting the fast movers and sequencing the pick list by aisle removes 202 m, 37% of the walking, and two-thirds of the crossings.

# Pickers work the list in the order the customer typed it, so the
# route zig-zags the length of the building instead of walking it once.
