OEE & Factory Performance worked example

Mean Time Between Stops with total run time of 1,100 hr: a worked example

What does the result look like when total run time reaches 1,100 hr? The full calculation is worked below with real intermediate numbers. Use it to size minor-stop and reliability problems in OEE & Factory Performance.

The inputs for this scenario

  • Total run time: 1,100 hr (raised for this scenario; the documented default is 420)
  • Number of stops: 14 stops (unchanged)
  • Normalization factor: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Mean time between stops = total run time ÷ number of stops × normalization factor) to the inputs above produces each figure below.
  • At this operating point the engine returns 78.57 hr for mean time between stops, the number this scenario is built around.
  • At this operating point the engine returns 78.57 value for raw ratio.
  • At this operating point the engine returns 1 x for conversion factor.
  • At this operating point the engine returns 14 value for denominator.

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 162% above the baseline at 78.57 hr.
  • A figure at this level is achievable when total run time is genuinely sustained, not just peaked for a shift. It is an average, so a handful of long runs can mask many micro-stops; pair it with a stop-count or Pareto view to see the full picture.

Results at a glance

  • Mean time between stops: 78.57 hr (headline result)
  • Raw ratio: 78.57 value
  • Conversion factor: 1 x
  • Denominator: 14 value
