Production worked example

OEE with planned production time of 240 min: a worked example

This worked example runs the oee numbers for a tougher week than the baseline: planned production time of 240 min instead of the typical 480 min. Calculate availability, performance, quality, and overall equipment effectiveness.

The inputs for this scenario

  • Planned production time: 240 min (the input this scenario stresses; the baseline uses 480)
  • Downtime: 55 min (held at the documented default)
  • Ideal cycle time: 20 sec / unit (held at the documented default)
  • Total count: 1,180 units (held at the documented default)
  • Good count: 1,125 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Availability = run time รท planned time.
  • OEE works out to 156 % at these inputs, and this is the headline figure for the scenario.
  • Availability works out to 77.08 % at these inputs.
  • Performance works out to 213 % at these inputs.
  • Quality works out to 95.34 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where planned production time sits at 480 min and the headline result is 78.12 %, this scenario comes in 100% above the baseline at 156 %.
  • Use it at the end of a shift, run, or day to score how much of your scheduled time produced good parts and to isolate which loss bucket is hurting most. 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.
