Ceramic Scrap Rework at 92% target rework capacity utilization: a worked example

This scenario runs the ceramic scrap rework calculation on the strong side: 92% target rework capacity utilization, with every other input held at its documented default. a ceramic plant needs to know whether scrap recovery capacity can handle current defects and holds

The inputs for this scenario

  • Rework hours or pieces used for ceramic scrap recovery: 18 hr or pieces (unchanged)
  • Available rework capacity for the period: 24 hr or pieces (unchanged)
  • Target rework capacity utilization: 92 % (raised for this scenario; the documented default is 80)

Working through the calculation

  • Applying the documented formula (Ceramic Scrap Rework = used capacity ÷ available capacity × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 75 % rework utilization for ceramic scrap rework, the number this scenario is built around.
  • At this operating point the engine returns 17 points for ceramic scrap rework gap to target.
  • At this operating point the engine returns 18 value for rework hours or pieces used for ceramic scrap recovery.
  • At this operating point the engine returns 24 value for available rework capacity for the period.

How this compares with the baseline

  • Against the tool's baseline example, where target rework capacity utilization sits at 80% and the headline result is 75 % rework utilization, this scenario lands almost exactly on the baseline at 75 % rework utilization.
  • Use it during shift or weekly capacity reviews to see whether rework effort is balanced against first-run production and your recovery 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

  • Ceramic Scrap Rework: 75 % rework utilization (headline result)
