Actuator Test Capacity at 99% test bench uptime: a worked example

What does the result look like when test bench uptime reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when loading a new bed model onto the actuator test bench and you need to confirm whether the bench can clear the week's production build.

The inputs for this scenario

  • Actuators tested per bench setup: 4 units / setup (unchanged)
  • Available bench setups per shift: 30 setups (unchanged)
  • Test bench uptime: 99 % (raised for this scenario; the documented default is 92)
  • Actuator first-pass acceptance rate: 96 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross actuator test throughput = actuators per setup × available setups per shift) to the inputs above produces each figure below.
  • At this operating point the engine returns 114 units for net accepted actuators per shift, the number this scenario is built around.
  • At this operating point the engine returns 120 units for gross actuator test throughput.
  • At this operating point the engine returns 1.2 units for units lost to bench downtime.
  • At this operating point the engine returns 4.75 units for units lost to first-pass failures.

How this compares with the baseline

  • Against the tool's baseline example, where test bench uptime sits at 92% and the headline result is 106 units, this scenario comes in 7.61% above the baseline at 114 units.
  • A figure at this level is achievable when test bench uptime is genuinely sustained, not just peaked for a shift. It assumes uptime and acceptance are independent and steady across the shift; a single failed life-cycle fixture or a bad actuator lot can break that assumption mid-shift.

Results at a glance

  • Net accepted actuators per shift: 114 units (headline result)
  • Gross actuator test throughput: 120 units
  • Units lost to bench downtime: 1.2 units
  • Units lost to first-pass failures: 4.75 units
