Maintenance Interval at 5.76% pm setup and execution time allowance: a worked example in hospital equipment & clinical furniture

This worked example runs the maintenance interval numbers for a tougher week than the baseline: 5.76% pm setup and execution time allowance instead of the typical 8%. Estimate the planned maintenance interval window for hospital equipment production machinery, including time to reach the PM trigger, setup, and maintenance execution time.

The inputs for this scenario

  • Production operations between PM events: 500 operations (held at the documented default)
  • Production rate at this station: 2 operations / min (held at the documented default)
  • PM setup and execution time allowance: 5.76 % (the input this scenario stresses; the baseline uses 8)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base interval runtime = operations between PM events รท production rate (minutes).
  • Total maintenance interval window works out to 264 hr at these inputs, and this is the headline figure for the scenario.
  • Base interval runtime works out to 250 hr at these inputs.
  • PM setup and execution allowance applied works out to 5.76 % at these inputs.
  • Production rate at this station works out to 2 pieces / min at these inputs.

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 2.07% below the baseline at 264 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. 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.

Results at a glance

  • Total maintenance interval window: 264 hr (headline result)
  • Base interval runtime: 250 hr
  • PM setup and execution allowance applied: 5.76 %
  • Production rate at this station: 2 pieces / min

Run it with your numbers
