Electronics Repair, Refurbishment & Depot Operations worked example

Test Fixture Utilization at 68% target fixture utilization: a worked example in electronics repair, refurbishment & depot operations

Suppose target fixture utilization falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Measure how much of the available diagnostic, functional test, programming, or burn-in fixture time is actually used by repair or refurbishment work.

The inputs for this scenario

  • Fixture hours actually run on board test: 8 fixture hr (held at the documented default)
  • Fixture hours available on the depot calendar: 250 fixture hr (held at the documented default)
  • Target fixture utilization: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Test fixture utilization = fixture hours used ÷ fixture hours available × 100.
  • Test fixture utilization works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Fixture utilization gap to target works out to 64.8 points at these inputs.
  • Fixture hours used works out to 8 count at these inputs.
  • Fixture hours available works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target fixture utilization sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the percentage of available test-fixture hours that were actually used to run boards, plus the point gap to your utilization 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

  • Test fixture utilization: 3.2 % (headline result)
  • Fixture utilization gap to target: 64.8 points
  • Fixture hours used: 8 count
  • Fixture hours available: 250 count
