Fuel System Test Capacity at 66% fuel-test bench uptime: a worked example

Suppose fuel-test bench uptime falls to 66%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate good fuel systems tested per shift from units per cycle, available bench cycles, bench uptime, and test pass rate.

The inputs for this scenario

  • Fuel systems tested per cycle: 6 units / cycle (held at the documented default)
  • Available fuel-test cycles: 420 cycles (held at the documented default)
  • Fuel-test bench uptime: 66 % (the input this scenario stresses; the baseline uses 92)
  • Fuel-test pass rate: 95 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross fuel-test throughput = fuel systems tested per cycle × available fuel-test cycles.
  • Good fuel systems tested per shift works out to 1,580 units at these inputs, and this is the headline figure for the scenario.
  • Gross fuel-test throughput works out to 2,520 units at these inputs.
  • Fuel-test downtime loss works out to 857 units at these inputs.
  • Fuel-test retest loss works out to 83.16 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where fuel-test bench uptime sits at 92% and the headline result is 2,202 units, this scenario comes in 28.26% below the baseline at 1,580 units.
  • It computes good fuel systems verified per shift after applying bench uptime and pass rate to gross test throughput. 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

  • Good fuel systems tested per shift: 1,580 units (headline result)
  • Gross fuel-test throughput: 2,520 units
  • Fuel-test downtime loss: 857 units
  • Fuel-test retest loss: 83.16 units
