Label Verification Sample Size at 65% verification station uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop verification station uptime to 65%, then walk the calculation through step by step. Estimate label verification sample size for traceability, serialization and lot genealogy using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Labels verified per inspection cycle: 4 units / cycle (held at the documented default)
  • Available inspection cycles in the window: 480 cycles (held at the documented default)
  • Verification station uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Label first-pass verification yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross label verification sample size capacity = label verification sample size output per cycle × available label verification sample size cycles.
  • Good label verification sample size capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross label verification sample size capacity works out to 1,920 units at these inputs.
  • Label verification sample size downtime loss works out to 672 units at these inputs.
  • Label verification sample size yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where verification 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 verification station uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single derating chain and does not model re-verification of failed labels, queueing, or variation between shifts and label formats.

Results at a glance

  • Good label verification sample size capacity: 1,211 units (headline result)
  • Gross label verification sample size capacity: 1,920 units
  • Label verification sample size downtime loss: 672 units
  • Label verification sample size yield loss: 37.44 units
