Abstract

fetched live from OpenAlex

Schedules for manufacturing cells can be systematically derived by simple stepwise refinements which, in consecutive steps, increase the complexity of the cell by introducing its components one after another. Timed Petri net models of schedules derived in this way have some convenient structural properties-net models are covered by conflict-free subnets, determined by place invariants of the model. These place invariant implied subnets can be used for evaluation of the basic performance characteristics of the model. The paper shows that place invariants of net models of schedules can be obtained by the same stepwise refinements that are used for model derivation. Simple examples of performance evaluation are included as an illustration of the use of place invariants in the analysis of schedules.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
