OEE & Factory Performance worked example

Availability Calculator with operating time of 1,100 hr: a worked example

Push operating time up to 1,100 hr and the picture changes. This example computes every intermediate figure at that operating point. Use it as the availability pillar of OEE in OEE & Factory Performance.

The inputs for this scenario

  • Operating (run) time: 1,100 hr (raised for this scenario; the documented default is 420)
  • Planned production time: 480 hr (unchanged)

Working through the calculation

  • Applying the documented formula (Availability = operating time รท planned production time) to the inputs above produces each figure below.
  • At this operating point the engine returns 229 % for availability, the number this scenario is built around.
  • At this operating point the engine returns 1,100 hr for operating time.
  • At this operating point the engine returns 480 hr for planned production time.
  • At this operating point the engine returns 0 hr for downtime.

How this compares with the baseline

  • Against the tool's baseline example, where operating time sits at 420 hr and the headline result is 87.5 %, this scenario comes in 162% above the baseline at 229 %.
  • It computes availability as operating run time divided by planned production time, plus the resulting downtime in hours. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Availability: 229 % (headline result)
  • Operating time: 1,100 hr
  • Planned production time: 480 hr
  • Downtime: 0 hr
