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.
