A warehouse has a fixed footprint of pallet positions. Several product families compete for that space based on their demand and pallet size. This tool sizes each storage zone, flags when you run out of room, and tells you how many warehouses you truly need.
Warehouse layout and slotting decide travel time - the biggest picking cost.
Fast movers near the dock cut travel; zones and aisles shape congestion.
Slot by velocity, re-slot seasonally, and keep golden zones for A items.
