What Is OEE?
- OEE measures how effectively a manufacturing operation is utilized compared to full potential.
- It combines Availability, Performance, and Quality in one score.
OEE Formula
- OEE (%) = Availability × Performance × Quality × 100
OEE Components Explained
- Availability = Operating Time / Planned Production Time.
- Performance = (Actual Output × Ideal Cycle Time) / Operating Time.
- Quality = Good Output / Total Output.
Step-by-Step OEE Calculation
- Step 1: Availability with Operating Time 420 and Planned Time 480 gives 420/480 = 0.875.
- Step 2: Performance with Output 800 and Ideal Cycle 0.5 gives (800×0.5)/420 = 0.95.
- Step 3: Quality with Good Output 780 and Total 800 gives 780/800 = 0.975.
- Step 4: OEE = 0.875 × 0.95 × 0.975 × 100 = 81.1%.
OEE Benchmark
- Below 60%: Poor.
- 60% to 75%: Average.
- 75% to 85%: Good.
- 85%+: World Class.
Six Big Losses in OEE
- Breakdown loss.
- Setup/changeover loss.
- Idling/minor stoppage loss.
- Speed loss.
- Defect loss.
- Startup/restart loss.
How to Improve OEE
- Reduce downtime with preventive maintenance.
- Improve performance by optimizing speed and method.
- Improve quality by reducing defects and rework.
- Train operators for stable process control.
OEE vs Efficiency
- OEE is a composite machine performance metric (APQ).
- Efficiency is usually a narrower output metric.
Practical Industrial Use
- Monitor machine performance.
- Identify production losses.
- Improve productivity.
- Increase profitability.
