Rubber, Tires, Foam & Elastomer Manufacturing worked example

Mixing Batch Yield at 99% target batch acceptance rate: a worked example

This scenario runs the mixing batch yield calculation on the strong side: 99% target batch acceptance rate, with every other input held at its documented default. Use it when mixing batch yield in rubber, tires, foam and elastomer manufacturing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Off-spec mixing batches: 8 count (unchanged)
  • Total mixing batches produced: 250 count (unchanged)
  • Target batch acceptance rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Mixing batch yield rate = mixing batch yield count ÷ total mixing batch yield population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for mixing batch yield rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for mixing batch yield gap to target.
  • At this operating point the engine returns 8 count for mixing batch yield count.
  • At this operating point the engine returns 250 count for total mixing batch yield population.

How this compares with the baseline

  • Against the tool's baseline example, where target batch acceptance rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it for weekly or monthly mixing-room reviews, or to check whether a new compound or mixer setting is holding acceptance. 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

  • Mixing batch yield rate: 3.2 % (headline result)
  • Mixing batch yield gap to target: 95.8 points
  • Mixing batch yield count: 8 count
  • Total mixing batch yield population: 250 count
