Data Source and Methodology
All calculations are based on the widely accepted OEE methodology. For more details, visit the OEE website. All calculations are strictly based on the formulas and data provided by this source.
The Formula Explained
OEE = Availability × Performance × Quality
Glossary of Terms
- Availability: The actual operating time divided by the planned production time.
- Performance: The ideal cycle time divided by the actual cycle time.
- Quality: The number of good units produced divided by the total units produced.
Practical Example
For a machine with 90% Availability, 85% Performance, and 95% Quality, the OEE would be calculated as:
OEE = 90% × 85% × 95% = 72.675%
Frequently Asked Questions (FAQ)
What is OEE?
OEE is a measure of how well a manufacturing operation is utilized compared to its full potential, during the periods when it is scheduled to run.
How can OEE be improved?
Improving OEE involves reducing downtime, speeding up production processes, and minimizing defects.
Why is OEE important?
OEE provides a benchmark for measuring the efficiency of manufacturing processes and a framework for continuous improvement.
What is a good OEE score?
An OEE score of 85% is considered world-class for discrete manufacturers.
How is OEE calculated in real-time?
Real-time OEE calculation requires integration with manufacturing execution systems (MES) and data collection tools.
