Manpower Calculator — Calculate Operators Needed for a Production Target
Before a new style starts, planners need to know how many operators a line needs to hit a required daily output — this reverses the usual target calculation to solve for manpower instead.
What is Manpower Calculation?
Before a new style starts, planners need to know how many operators a line needs to hit a required daily output — this reverses the usual target calculation to solve for manpower instead.
Formula
Manpower Required = (Target Output × SMV) / (Working Minutes × Efficiency%/100)
Result is rounded up to the next whole operator.
How to Calculate
Multiply target pieces by garment SMV, then divide by total available working minutes multiplied by line efficiency percentage. Round up to the next integer.
Example
Target=10,000 pcs/day, SMV=0.75, Working Minutes=600, Efficiency=60% → 20.83 → 21 operators.
Frequently Asked Questions
Because you can't staff a fractional operator — rounding down would understaff the line and make the target unreachable.
