Abstract

fetched live from OpenAlex

Industrial manufacturing environments often penalize job earliness and tardiness or the sum of setup times, yet little work has addressed the combination of these complexities. This thesis formalizes and investigates the Earliness Tardiness Scheduling with Setups (ETSS) problem, which is a single machine scheduling problem minimizing weighted earliness/tardiness and setup costs. We develop several solution methodologies utilizing the following optimization techniques: Integer Programming (MIP), Constraint Programming (CP), Decisions Diagrams (DD), and Large Neighbourhood Search (LNS). Our computational studies demonstrate scalability issues with the complex objective function and find that LNS is the best technique developed, suggesting that LNS is an appropriate method for solving the ETSS problem.

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.
