Abstract

fetched live from OpenAlex

A systematic control strategy is proposed for the optimal operation of multi-unit systems undergoing a partial shutdown. The strategy entails manipulating the degrees-of-freedom available during and after a shutdown such that production is restored in a cost-optimal fashion while meeting all safety and operational constraints. In this work, we investigate the coordination of buffer tanks, production rates and recycle streams during a partial shutdown. The problem is cast as a nonlinear dynamic optimization problem. Disturbances are handled using a nonlinear predictive controller that is explicitly aware of shutdown events.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
