Line Rate at 99% expected line efficiency: a worked example
Push expected line efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. an operations manager needs a realistic hourly rate for scheduling, labor, or downstream capacity checks
The inputs for this scenario
- Active producing lanes or stations: 3 lanes (unchanged)
- Standard output per lane-hour: 420 units / lane-hr (unchanged)
- Expected line efficiency: 99 % (raised for this scenario; the documented default is 86)
Working through the calculation
- Applying the documented formula (Theoretical line rate = active lanes × standard output per lane-hour) to the inputs above produces each figure below.
- At this operating point the engine returns 1,247 units / hr for effective line rate, the number this scenario is built around.
- At this operating point the engine returns 1,260 units / hr for theoretical line rate.
- At this operating point the engine returns 12.6 units / hr for rate lost to inefficiency.
- At this operating point the engine returns 99 % for line efficiency.
How this compares with the baseline
- Against the tool's baseline example, where expected line efficiency sits at 86% and the headline result is 1,084 units / hr, this scenario comes in 15.12% above the baseline at 1,247 units / hr.
- It computes the effective output in units per hour by multiplying active lanes by standard per-lane output, then derating for line efficiency. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
