- OEE
- 71.1 %
- Availability
- 87.5 %
- Performance
- 83.3 %
- Quality
- 97.5 %
Formula
Availability = (planned − downtime) ÷ planned
Performance = ideal cycle × total count ÷ run time
Quality = good ÷ total
OEE = A × P × Q
Assumptions & limits
- Planned time excludes scheduled breaks.
- World-class OEE is often quoted as ≈ 85%.
Worked example
A = 420/480 = 87.5%; P = 21,000 s ÷ 25,200 s = 83.3%; Q = 97.5% → OEE 71.1%.
