Analytical Proof & Invariants

Machine Precision

Governing Mathematical Formula:

Units Per Hour (UPH) = Total Units Picked / Total Net Warehouse Labor Hours

Step-by-Step Mathematical Derivation

Total Labor Hours

Labor Hours = 4 pickers × 8 hours = 32.0 man-hours.

Productivity Benchmark (UPH)

UPH = 2,400 units / 32 hours = 75.0 Units Per Hour per picker.

Cost Per Pick Unit

Daily Payroll = 32 hours × $21.50/hr = $688.00. Cost per item = $688.00 / 2,400 units = $0.287 per pick.

Cycle Time Conversion

Time per Pick = 3,600 seconds / 75 UPH = 48.0 seconds per item picked.

Frequently Asked Questions

What is an industry standard UPH for e-commerce picking? +

In manual cart-picking operations, standard UPH ranges from 60 to 90 units per hour. With batch picking and voice/pick-to-light sorting, UPH reaches 150 to 250 UPH. Autonomous mobile robots (AMRs) can achieve 300+ UPH.

What consumes the most time during order picking? +

Walking travel time between rack locations typically accounts for 50% to 65% of an order picker's entire shift. Optimizing bin slotting and ABC inventory velocity drastically reduces wasted footsteps.
