Maintenance Interval at 9.2% pm setup and execution time allowance: a worked example in hospital equipment & clinical furniture

This scenario runs the maintenance interval calculation on the strong side: 9.2% pm setup and execution time allowance, with every other input held at its documented default. Use it when scheduling preventive maintenance for hospital equipment production equipment such as tube benders, weld fixtures, powder coat ovens, upholstery sewing tables, or assembly torque tools.

The inputs for this scenario

  • Production operations between PM events: 500 operations (unchanged)
  • Production rate at this station: 2 operations / min (unchanged)
  • PM setup and execution time allowance: 9.2 % (raised for this scenario; the documented default is 8)

Working through the calculation

  • Applying the documented formula (Base interval runtime = operations between PM events รท production rate (minutes)) to the inputs above produces each figure below.
  • At this operating point the engine returns 273 hr for total maintenance interval window, the number this scenario is built around.
  • At this operating point the engine returns 250 hr for base interval runtime.
  • At this operating point the engine returns 9.2 % for pm setup and execution allowance applied.
  • At this operating point the engine returns 2 pieces / min for production rate at this station.

How this compares with the baseline

  • Against the tool's baseline example, where pm setup and execution time allowance sits at 8% and the headline result is 270 hr, this scenario comes in 1.11% above the baseline at 273 hr.
  • Use it when scheduling preventive maintenance on a station whose PM trigger is defined by an operation or cycle count rather than by calendar time. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total maintenance interval window: 273 hr (headline result)
  • Base interval runtime: 250 hr
  • PM setup and execution allowance applied: 9.2 %
  • Production rate at this station: 2 pieces / min
