The optimiser computes the number inside the signed window; the agent explains it. People with the right accept, adjust in band or decline.

Process agent·Line A·Jacket loop·Hold temperature 84 to 86 °C·14:00TrialRunning trial

Batches held at 86 °C reached target viscosity 6 minutes sooner in the model of the mixer, inside the narrowed band.

Expected result

ModelledViscosity2470 mPa·s90% interval 2410 to 2540

Spec 2380 to 2600 mPa·s (dashed). Driven by Hold temperature, Hold time, Charge mass.

Why this confidence

Method: Optimiser opt 2.4.0; band from the model of the machine; weakest input modelled
Model fit: Accepted, four checks passed
Safety filter: Passed: Inside narrowed band 80 to 90 °C
Evidence: EV-A-1102, EV-A-1120
