OEE & Factory Performance worked example

Performance Efficiency with actual output of 460 units: a worked example

This worked example runs the performance efficiency numbers for a tougher week than the baseline: actual output of 460 units instead of the typical 920 units. Calculate performance efficiency for OEE & Factory Performance — actual output as a share of the rated-speed ideal.

The inputs for this scenario

  • Actual output: 460 units (the input this scenario stresses; the baseline uses 920)
  • Ideal output at rated speed: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Performance = actual output ÷ ideal output at rated speed.
  • Performance efficiency works out to 46 % at these inputs, and this is the headline figure for the scenario.
  • Actual output works out to 460 units at these inputs.
  • Ideal output works out to 1,000 units at these inputs.
  • Lost output works out to 540 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where actual output sits at 920 units and the headline result is 92 %, this scenario comes in 50% below the baseline at 46 %.
  • Use it whenever a line ran for its scheduled time but produced fewer units than its nameplate speed predicts, to isolate speed and minor-stop losses. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Performance efficiency: 46 % (headline result)
  • Actual output: 460 units
  • Ideal output: 1,000 units
  • Lost output: 540 units
