Serialized Part Control Load at 40% verification and correction allowance: a worked example

What does the result look like when verification and correction allowance reaches 40%? The full calculation is worked below with real intermediate numbers. a production or quality planner needs to estimate the effort to control serialized flight hardware through a lot

The inputs for this scenario

  • Serialized flight parts: 124 serialized parts (unchanged)
  • Serialization processing pace: 2.1 parts/min (unchanged)
  • Verification and correction allowance: 40 % (raised for this scenario; the documented default is 35)

Working through the calculation

  • Applying the documented formula (Base serialization processing time = serialized parts รท processing pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 82.67 serialization hr for serialized part control load, the number this scenario is built around.
  • At this operating point the engine returns 59.05 serialization hr for base serialization processing time.
  • At this operating point the engine returns 40 % for verification and correction allowance.
  • At this operating point the engine returns 2.1 parts/min for serialization processing pace.

How this compares with the baseline

  • Against the tool's baseline example, where verification and correction allowance sits at 35% and the headline result is 79.71 serialization hr, this scenario comes in 3.7% above the baseline at 82.67 serialization hr.
  • A figure at this level is achievable when verification and correction allowance is genuinely sustained, not just peaked for a shift. It assumes a steady processing pace; in practice mixed part families with different marking methods (laser etch vs. dot-peen vs. tag) will have very different paces and may need separate runs.

Results at a glance

  • Serialized part control load: 82.67 serialization hr (headline result)
  • Base serialization processing time: 59.05 serialization hr
  • Verification and correction allowance: 40 %
  • Serialization processing pace: 2.1 parts/min
