Assign Storage Areas
In warehouse operations, several methods are used to assign storage areas.
1) Fixed (Dedicated) Location – Each SKU is assigned a permanent storage location, facilitating direct putaway and retrieval but potentially reducing space utilization efficiency.
2) Categorical (Class-Based) Storage – Items are grouped and stored based on shared attributes such as size, weight, hazard classification, or temperature requirements (e.g., flammable storage, cold storage).
3) Randomized (Floating) Location – Storage locations are assigned dynamically based on real-time inventory levels and space availability, often managed through a warehouse management system (WMS) that optimizes slotting for space efficiency.
4) ABC Analysis – Storage is prioritized according to inventory turnover rates using Pareto classification (A: high-turnover SKUs, B: moderate, C: low), optimizing pick paths and minimizing travel time for frequently accessed stock.
Or a combination of the above.
Here are a few sample layouts.
Warehouse One – The receiving dock features a temporary inbound staging area, followed by quarantine and inspection zones for returned or damaged goods. Central warehouse zones (A, B, & C) utilize selective pallet racking for bulk goods, cantilever racks for long items, and shelving for small parts. Outbound staging is located near shipping docks. The inbound and outbound staging areas are designed to support cross-docking and accommodate 80% of fast-moving inventory within 20% of the available space, following the Pareto principle.
Warehouse Two – The facility begins with wide-span shelving for high-velocity SKUs, followed by carton flow racks and bin shelving for dense storage of small items. Floor-to-ceiling cantilever racks are used for large, irregular, or long products such as piping or lumber. A dedicated bay contains heavy-duty pallet racks and an automated storage and retrieval system (AS/RS) with stacker cranes for high-density, high-weight inventory management.
Warehouse Three – High-value inventory is stored in a secure cage near the main entrance with restricted access. Segregated storage areas are designated for fragile goods (using padded shelving), hazardous materials (in compliance with HAZMAT regulations and fire suppression systems), and bonded goods (under customs control). General storage utilizes adjustable pallet racking for room-temperature products. A temperature-controlled cold storage room with insulated doors houses refrigerated and frozen items, which are transported using battery-powered pallet jacks and reach trucks certified for low-temperature operation.
