Ceramic Production Ramp Planner at 90% ramp kiln and press uptime: a worked example

Push ramp kiln and press uptime up to 90% and the picture changes. This example computes every intermediate figure at that operating point. a production manager needs to plan good-part output during ramp-up of a new technical ceramic component

The inputs for this scenario

  • Good parts per fired ramp cycle: 180 parts/cycle (unchanged)
  • Planned ramp kiln cycles: 10 cycles (unchanged)
  • Ramp kiln and press uptime: 90 % (raised for this scenario; the documented default is 78)
  • First-pass sintered yield during ramp: 72 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross ramp output = parts per ramp cycle × planned ramp cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,166 good ramp parts for expected good ramp output, the number this scenario is built around.
  • At this operating point the engine returns 1,800 good ramp parts for gross ramp output.
  • At this operating point the engine returns 180 good ramp parts for ramp downtime loss.
  • At this operating point the engine returns 454 good ramp parts for ramp yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where ramp kiln and press uptime sits at 78% and the headline result is 1,011 good ramp parts, this scenario comes in 15.38% above the baseline at 1,166 good ramp parts.
  • It multiplies parts per cycle by planned cycles to get gross output, then derates that by kiln uptime and expected sinter yield to give expected good ramp output. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Expected good ramp output: 1,166 good ramp parts (headline result)
  • Gross ramp output: 1,800 good ramp parts
  • Ramp downtime loss: 180 good ramp parts
  • Ramp yield loss: 454 good ramp parts
