o   Forecast throughput (daily lines/orders) and peak activity to size receiving, picking, and staging areas.

o   Consider future growth so the layout remains scalable.

Step 2: Analyze inventory types and SKUs

• Classify SKUs by velocity (A/B/C), size, weight, and storage requirements (temperature, fragility).
• Determine slotting needs: bulk vs. racked storage, pallet vs. bin, and special handling for odd-sized items.
• Use SKU ABC analysis to allocate the best locations to high-turn items.

Step 3: Define functional zones

• Create clear zones for receiving, QA/inspection, bulk storage, racked storage, picking, packing, shipping, returns, and value-add (kitting/inspection).
• Size each zone based on activity data (e.g., receiving bays sized for peak inbound pallets).
• Plan buffer/staging areas to decouple upstream and downstream flows.

Step 4: Map out material flow

• Design a linear logical flow (receiving → storage → picking → packing → shipping) to minimize cross-traffic and backtracking.
• Place high-frequency SKUs close to packing and shipping to reduce travel time.
• Define one-way aisles and separate pedestrian and vehicle routes.

Step 5: Consider safety and compliance

• Ensure aisle widths, egress routes, and rack loading meet local codes and standards (e.g., fire and occupational safety).
• Allocate safe zones for hazardous materials and emergency equipment.
• Incorporate ergonomic pick heights and lift-assist areas to reduce injuries.

Step 6: Use CAD or layout design software

• Model options with CAD or specialized warehouse-layout tools to test scenarios, simulate picking paths, and calculate space utilization.
• Run simple simulations to compare travel distances, throughput, and dock utilization before committing to changes.

Step 7: Consult warehouse design professionals

• Engage material-handling engineers or logistics consultants for complex facilities, automation feasibility, and regulatory review.
• Validate designs against real-world constraints (equipment turning radii, forklift clearances, and maintenance access).

Studies (MIT Center for Transportation & Logistics, 2021) report improvements in order throughput of up to ~33% when layouts are optimized and slotting is data-driven. In short, a stepwise, data-led approach measures, classifies, zones, flows, validates, and consults to produce a warehouse layout that’s safe, efficient, and scalable.
