Order Pick Rate and Labour Standard
Builds an engineered pick standard from travel, pick, and per-unit elements with a setup and a PF and D allowance.
Example
You enter
- Lines per order 120
- Units per line 2.5
- Travel time per line (s) 18
- Pick time per line (s) 12
- Time per additional unit (s) 3
- Setup and close per order (min) 8
- Personal, fatigue, and delay allowance (%) 15
- Orders per batch 4
- Travel per line when batched (s) 7
You get
- Time per line 34.5 s
- Picking time 69.0 min before allowances
- Allowed order time 88.5 min
- Standard rate 81 lines/h, 203 units/h
- Units per hour 203.275
- Share of the time spent travelling 52% -- none of it touches a carton
- Batch time per line (s) 23.5
- Batch allowed order time (min) 63.25
- Batched rate 114 lines/h at 23.5 s per line
- What batching buys 40
Details, formula, and sources
Builds an engineered pick standard from travel, pick, and per-unit elements with a setup and a PF and D allowance, then reports lines and units per hour and the travel share. The worked order is 52% travel; batching lifts 81 lines/h to 114 and costs a sort.
Time per line = travel + pick + (units per line - 1) x per-additional-unit time; allowed order time = (line time + setup and close) x (1 + PF and D allowance); rate = lines / allowed time.
The facility's own time study or predetermined motion time system, and any applicable collective bargaining agreement where a standard is used to staff or to pay.
Element build-up is public method; the element times themselves are facility-specific measurements.

- PF and D allowance 10 to 20% is usual; entered rather than assumedfacility time study
- Batched travel entered rather than divided by the batch size -- the picker still walks between every location the combined order needsspec-v1817 method
