Parts Washer Utilization at 94% target washer utilization: a worked example

This scenario runs the parts washer utilization calculation on the strong side: 94% target washer utilization, with every other input held at its documented default. Use it when production managers need to understand whether a washer is underused, overloaded, or becoming a cleaning bottleneck.

The inputs for this scenario

  • Productive washer operating time: 13.5 hr (unchanged)
  • Available washer time: 16 hr (unchanged)
  • Target washer utilization: 94 % (raised for this scenario; the documented default is 82)

Working through the calculation

  • Applying the documented formula (Parts washer utilization rate = productive washer operating time ÷ available washer time × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 84.38 % for parts washer utilization rate, the number this scenario is built around.
  • At this operating point the engine returns 9.63 points for parts washer utilization gap to target.
  • At this operating point the engine returns 13.5 hr for productive washer operating time.
  • At this operating point the engine returns 16 hr for available washer time.

How this compares with the baseline

  • Against the tool's baseline example, where target washer utilization sits at 82% and the headline result is 84.38 %, this scenario lands almost exactly on the baseline at 84.38 %.
  • Use it for capacity reviews, shift-loading decisions, or before justifying a second washer or an added cleaning shift. 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

  • Parts washer utilization rate: 84.38 % (headline result)
