Actuator Test Capacity at 66% test bench uptime: a worked example

Suppose 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 how many hospital bed actuators can be tested and accepted per shift on your test bench, accounting for bench uptime and first-pass acceptance rate.

The inputs for this scenario

  • Actuators tested per bench setup: 4 units / setup (held at the documented default)
  • Available bench setups per shift: 30 setups (held at the documented default)
  • Test bench uptime: 66 % (the input this scenario stresses; the baseline uses 92)
  • Actuator first-pass acceptance rate: 96 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross actuator test throughput = actuators per setup × available setups per shift.
  • Net accepted actuators per shift works out to 76.03 units at these inputs, and this is the headline figure for the scenario.
  • Gross actuator test throughput works out to 120 units at these inputs.
  • Units lost to bench downtime works out to 40.8 units at these inputs.
  • Units lost to first-pass failures works out to 3.17 units at these inputs.

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 28.26% below the baseline at 76.03 units.
  • It computes net accepted actuators per shift by multiplying gross bench throughput by test-bench uptime and the first-pass acceptance rate. 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

  • Net accepted actuators per shift: 76.03 units (headline result)
  • Gross actuator test throughput: 120 units
  • Units lost to bench downtime: 40.8 units
  • Units lost to first-pass failures: 3.17 units

Run it with your numbers
