Parts Washer Utilization at 59% target washer utilization: a worked example

Suppose target washer utilization falls to 59%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate parts washer utilization from productive washer time, available washer time, and target utilization.

The inputs for this scenario

  • Productive washer operating time: 13.5 hr (held at the documented default)
  • Available washer time: 16 hr (held at the documented default)
  • Target washer utilization: 59 % (the input this scenario stresses; the baseline uses 82)

Working through the calculation

  • The calculation starts from the formula this tool documents: Parts washer utilization rate = productive washer operating time ÷ available washer time × 100.
  • Parts washer utilization rate works out to 84.38 % at these inputs, and this is the headline figure for the scenario.
  • Parts washer utilization gap to target works out to -25.37 points at these inputs.
  • Productive washer operating time works out to 13.5 hr at these inputs.
  • Available washer time works out to 16 hr at these inputs.

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 %.
  • It computes the percentage of available washer time spent in productive cleaning and the point gap between that rate and your target. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

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