Ceramic Scrap Rework at 58% target rework capacity utilization: a worked example

Suppose target rework capacity utilization falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Measure how much available ceramic rework capacity is being used to recover scrap or held ware.

The inputs for this scenario

  • Rework hours or pieces used for ceramic scrap recovery: 18 hr or pieces (held at the documented default)
  • Available rework capacity for the period: 24 hr or pieces (held at the documented default)
  • Target rework capacity utilization: 58 % (the input this scenario stresses; the baseline uses 80)

Working through the calculation

  • The calculation starts from the formula this tool documents: Ceramic Scrap Rework = used capacity ÷ available capacity × 100.
  • Ceramic Scrap Rework works out to 75 % rework utilization at these inputs, and this is the headline figure for the scenario.
  • Ceramic Scrap Rework gap to target works out to -17 points at these inputs.
  • Rework hours or pieces used for ceramic scrap recovery works out to 18 value at these inputs.
  • Available rework capacity for the period works out to 24 value at these inputs.

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.
  • It divides rework capacity used for ceramic scrap recovery by available rework capacity to give a utilization percentage, then compares it to your target to show the gap. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
