Calculation method
Calculation method
Required worker-hours
Harvest quantity / measured individual picking rate.
Elapsed crew hours
Worker-hours / crew size, assuming divisible work.
Whole working days touched
Round up elapsed crew hours / working hours per day.
Symbols and units
- a
- Harvest quantity (kg)
- b
- Measured picking rate (kg/worker-hour)
- c
- Workers
- d
- Working hours per day
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Uses your measured constant rate, with evenly divisible work. Rest, travel, ripeness, packaging, weather and bottlenecks can increase actual time. A partial final day counts as a day touched, not a fully worked day.
