How the Algorithm Works
The optimizer runs four sequential passes against the SKU catalogue and warehouse geometry, building a slot assignment that maximizes throughput while keeping pickers in ergonomically safe positions.
1 · Velocity Scoring
Every SKU is ranked by weekly pick frequency: the single strongest predictor of travel-time cost. A-tier SKUs (100+ picks/week) represent ~70% of all picks despite being only 26% of SKUs.
2 · Weight Constraint
SKUs weighing 30 lb or more are flagged as floor-level (Level L) items regardless of pick frequency. Forcing pickers to reach overhead for 40 lb generators violates OSHA ergonomic guidelines and drives injury claims.
3 · Ergonomic Zone Assignment
Slots are classified A (waist-height, bays 1-3, aisles A-C), B (good), or C (poor). Zone A is reserved for A-tier light-weight SKUs. The 'golden zone' alone captures 69% of total picks.
4 · Category Affinity Clustering
Within each velocity tier, SKUs sharing the same product category receive adjacent slot assignments. This reduces cross-aisle travel when a single order contains multiple items from the same category: common in e-commerce fulfillment.
