Traceability, Serialization & Lot Genealogy worked example

Genealogy Lookup Time at 12% setup, navigation, and system-delay allowance: a worked example

What does the result look like when setup, navigation, and system-delay allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when genealogy lookup time in traceability, serialization and lot genealogy needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Genealogy records to trace: 120 units (unchanged)
  • Records traced per minute: 12 units / min (unchanged)
  • Setup, navigation, and system-delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base genealogy lookup time = genealogy lookup time workload รท genealogy lookup time completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required genealogy lookup time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base genealogy lookup time.
  • At this operating point the engine returns 12 % for genealogy lookup time allowance applied.
  • At this operating point the engine returns 12 pieces / min for genealogy lookup time completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, navigation, and system-delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when setup, navigation, and system-delay allowance is genuinely sustained, not just peaked for a shift. It assumes a steady average lookup rate; a broken or forked genealogy chain with missing links can stall a single record far longer than the average predicts.

Results at a glance

  • Required genealogy lookup time: 11.2 hr (headline result)
  • Base genealogy lookup time: 10 hr
  • Genealogy lookup time allowance applied: 12 %
  • Genealogy lookup time completion rate: 12 pieces / min
