OEE & Factory Performance worked example
Cycle Time Loss with actual cycle time of 80 sec / unit: a worked example
What does the result look like when actual cycle time reaches 80 sec / unit? The full calculation is worked below with real intermediate numbers. Use it to size the performance loss in OEE for OEE & Factory Performance.
The inputs for this scenario
- Actual cycle time: 80 sec / unit (raised for this scenario; the documented default is 32)
- Ideal cycle time: 28 sec / unit (unchanged)
- Units produced: 1,500 units (unchanged)
Working through the calculation
- Applying the documented formula (Cycle-time loss = (actual cycle − ideal cycle) × units ÷ 60) to the inputs above produces each figure below.
- At this operating point the engine returns 1,300 min for cycle-time loss, the number this scenario is built around.
- At this operating point the engine returns 52 sec / unit for loss per unit.
- At this operating point the engine returns 1,500 units for units.
- At this operating point the engine returns 21.67 hr for loss in hours.
How this compares with the baseline
- Against the tool's baseline example, where actual cycle time sits at 32 sec / unit and the headline result is 100 min, this scenario comes in 1,200% above the baseline at 1,300 min.
- A figure at this level is achievable when actual cycle time is genuinely sustained, not just peaked for a shift. It only captures speed loss versus your chosen ideal cycle; it does not account for downtime or quality losses, and an unrealistic ideal cycle skews the result.
