Line Yield Loss at 1.73% target line loss rate: a worked example

This scenario runs the line yield loss calculation on the strong side: 1.73% target line loss rate, with every other input held at its documented default. Use it when production teams need to quantify losses from hot-end rejects, cold-end inspection rejects, breakage, lehr losses, handling damage, packer rejects, or held ware.

The inputs for this scenario

  • Lost containers on the line: 2,600 containers (unchanged)
  • Total formed containers: 145,000 containers (unchanged)
  • Target line loss rate: 1.73 % (raised for this scenario; the documented default is 1.5)

Working through the calculation

  • Applying the documented formula (Line yield loss rate = lost containers on line ÷ total formed containers × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 1.79 % for line yield loss rate, the number this scenario is built around.
  • At this operating point the engine returns -0.06 points for line loss gap to target.
  • At this operating point the engine returns 2,600 count for lost containers on line.
  • At this operating point the engine returns 145,000 count for total formed containers.

How this compares with the baseline

  • Against the tool's baseline example, where target line loss rate sits at 1.5% and the headline result is 1.79 %, this scenario lands almost exactly on the baseline at 1.79 %.
  • Use it for daily or shift yield reviews, campaign post-mortems, and to flag when a job is drifting away from its loss target. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Line yield loss rate: 1.79 % (headline result)
  • Line loss gap to target: -0.06 points
  • Lost containers on line: 2,600 count
  • Total formed containers: 145,000 count
