Calculation method
Calculation method
Total lines
Add the supplied line counts.
Total worker-hours
Total lines / measured worker rate.
Elapsed wave hours
Worker-hours / actual workers, assuming divisible work.
Workers needed within shift
Round up worker-hours / available shift hours.
Symbols and units
- a
- Order-line counts
- b
- Measured lines per worker-hour
- c
- Workers
- d
- Available shift hours
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
- A divisible-work model at constant measured productivity. Order dependencies, travel congestion, breaks and indivisible assignments can lengthen elapsed time.
