Repair Depot Throughput at 65% expected repair bench uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop expected repair bench uptime to 65%, then walk the calculation through step by step. Estimate repair depot capacity for field-returned rugged electronics, mission computers, radios, power supplies, sensors, or replaceable modules.

The inputs for this scenario

  • Units repaired per depot cycle: 4 units / cycle (held at the documented default)
  • Available depot repair cycles: 480 cycles (held at the documented default)
  • Expected repair bench uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass repair yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross depot repair capacity = units repaired per depot cycle × available depot repair cycles.
  • Released repair depot throughput works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross depot repair capacity works out to 1,920 units at these inputs.
  • Repair bench downtime loss works out to 672 units at these inputs.
  • Repair retest yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected repair bench uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to expected repair bench uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. First-pass yield here removes units that need rework rather than recovering them; if your process reworks and re-releases failed units, actual released volume will be somewhat higher than this conservative estimate.

Results at a glance

  • Released repair depot throughput: 1,211 units (headline result)
  • Gross depot repair capacity: 1,920 units
  • Repair bench downtime loss: 672 units
  • Repair retest yield loss: 37.44 units
