Warehouse Slotting Simulator
Assign SKU slot positions by pick velocity with hot/warm/cold zones and golden-zone scoring.
Warehouse Slotting Simulator
Upload SKU velocity data to simulate an optimized warehouse slotting layout. Configure aisles, bays per aisle, and levels. Set hot/warm/cold zone thresholds. The simulator assigns highest-velocity SKUs to positions closest to the staging area at the golden-zone (middle) level, minimizing pick travel. Visual top-down floor plan with color-coded zones, per-level view selector, and efficiency metrics. CSV export of assignments.

Why Slotting Matters
Pickers spend more than half their time walking. Optimized slotting — placing high-velocity SKUs closer to the staging area and at waist-height "golden zone" positions — directly reduces pick travel time and fatigue. Well-slotted warehouses can achieve 30-50% higher pick rates than poorly slotted ones with the same layout.
Hot / Warm / Cold Zones
The simulator divides slots into three velocity zones. Hot-zone SKUs (typically the top 20% by picks) get the best positions — closest to shipping, middle-level shelves. Warm-zone SKUs fill the next tier of positions. Cold-zone SKUs go to the back aisles and top/bottom shelves. This Pareto-driven placement often follows the ABC classification — feed data from the ABC Analysis Tool for consistency.
Beyond the Simulation
Real-world slotting has to account for SKU dimensions, weight, compatibility (can't slot chemicals next to food), seasonality, and family grouping (related SKUs picked together should be near each other). This tool provides the baseline velocity-driven plan — use it as a starting point for more detailed slotting analysis.
