OEE & Factory Performance worked example

Mean Time Between Stops with total run time of 210 hr: a worked example

Suppose total run time falls to 210 hr. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate mean time between stops for OEE & Factory Performance from run time and the number of stoppages.

The inputs for this scenario

  • Total run time: 210 hr (the input this scenario stresses; the baseline uses 420)
  • Number of stops: 14 stops (held at the documented default)
  • Normalization factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Mean time between stops = total run time ÷ number of stops × normalization factor.
  • Mean time between stops works out to 15 hr at these inputs, and this is the headline figure for the scenario.
  • Raw ratio works out to 15 value at these inputs.
  • Conversion factor works out to 1 x at these inputs.
  • Denominator works out to 14 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where total run time sits at 420 hr and the headline result is 30 hr, this scenario comes in 50% below the baseline at 15 hr.
  • It divides total run time by the number of stops, then applies a normalization factor, to give the average run length between interruptions. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Mean time between stops: 15 hr (headline result)
  • Raw ratio: 15 value
  • Conversion factor: 1 x
  • Denominator: 14 value

Run it with your numbers

  • To rerun this with your own numbers, open the live Mean Time Between Stops calculator, set total run time to your actual value, and adjust the remaining inputs to match your operation.
