Abstract

fetched live from OpenAlex

This paper deals with the problem of scheduling tasks in flow shop environment with the presence of operators. The assignment of operators changes according to the end of operation changing mode. We investigate two problems: the first is that of handling simultaneously the operators and the tasks while in the second, the assignment of operators is made subject to a fixed task sequence. We seek to quantify the impact of operators and see to what extent adding an operator can improve the quality of a solution. We found that the utility of adding an operator depends on the size of instances, particularly on the number of machines.

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.
