Calculation Method:
OEE = Availability × Performance × Quality.
Availability = (Planned Time − Downtime) / Planned Time;
Performance = (Total Output × Ideal Cycle Time) / Actual Run Time;
Quality = Good Units / Total Output.
The world-class OEE benchmark is 85% (Availability 90% × Performance 95% × Quality 99.9%).
In the semiconductor industry, actual OEE typically ranges between 60% and 80% due to process complexity.
