Using Warehouse Layout Simulator
Design a warehouse grid with racks and docks, inspect simplified single-picker routes and traversal heatmaps, and compare sampled-demand scenarios.
Workflow
Set the grid and place racks, docks, and walkable aisles; check that the layout connects the requested docks.
Create pick tasks or run a sampled-demand scenario, then inspect the selected route and traversal heatmap.
Compare alternative demand samples and filters, review quality warnings, and export a route report or project backup.
Worked example
Lay out two docks with rack aisles connected by walkable paths, then create a small pick list across several racks. Inspect the selected multi-dock route and traversal heatmap before comparing another demand sample.
Limits and data handling
The model uses one picker on a four-neighbor walkable grid, greedy nearest-stop routes, and uniformly sampled rack demand. Heatmap counts show traversal, not congestion. Twelve demand seeds are alternate samples, not forecast confidence intervals. It does not assess forklifts, turning clearance, rack loading, fire egress, labor planning, or safety compliance. The grid is limited to 60 by 40 cells and 500 tasks.
Frequently asked questions
Does the heatmap show congestion or worker density?
No. It counts route traversal through cells; it does not model congestion, multiple pickers, or worker density.
Does the route model forklifts or certify aisle safety?
No. It models one picker on a four-neighbor grid and does not assess forklift movement, clearances, rack loading, fire egress, or safety.
