Inspection Throughput at 63% practical inspection efficiency: a worked example

Suppose practical inspection efficiency falls to 63%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate effective fiber optic inspection throughput from completed inspections, runtime, and practical inspection efficiency.

The inputs for this scenario

  • Completed end-face inspections: 1,200 inspections (held at the documented default)
  • Inspection station runtime: 8 hr (held at the documented default)
  • Practical inspection efficiency: 63 % (the input this scenario stresses; the baseline uses 88)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw inspection throughput = completed inspections รท inspection runtime.
  • Effective optical inspection throughput works out to 94.5 units / hr at these inputs, and this is the headline figure for the scenario.
  • Raw inspection throughput works out to 150 units / hr at these inputs.
  • Efficiency works out to 63 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where practical inspection efficiency sits at 88% and the headline result is 132 units / hr, this scenario comes in 28.41% below the baseline at 94.5 units / hr.
  • It computes effective inspection throughput by dividing completed inspections by station runtime, then derating that raw rate by your practical inspection efficiency. 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

  • Effective optical inspection throughput: 94.5 units / hr (headline result)
  • Raw inspection throughput: 150 units / hr
  • Efficiency: 63 %
  • Runtime: 8 hr

Run it with your numbers
