Compliance Sample Quantity at 65% expected test-station uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop expected test-station uptime to 65%, then walk the calculation through step by step. Estimate compliance sample quantity for security, fire and life safety products using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Compliance test samples completed per inspection cycle: 4 units / cycle (held at the documented default)
  • Available inspection cycles in the period: 480 cycles (held at the documented default)
  • Expected test-station uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass compliance yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross compliance sample quantity capacity = compliance sample quantity output per cycle × available compliance sample quantity cycles.
  • Good compliance sample quantity capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross compliance sample quantity capacity works out to 1,920 units at these inputs.
  • Compliance sample quantity downtime loss works out to 672 units at these inputs.
  • Compliance sample quantity 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 test-station 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 test-station uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It models uptime and yield as flat averages; a single long station outage or a bad lot can move actual results well off the calculated figure.
