Analyse fiabiliste des propriétés structurelles des systèmes continus par les réseaux d’activités stochastiques
Bibliographic record
Abstract
Dans cet article, nous montrons une approche originale de couplage entre l’analyse des systèmes continus et celle des systèmes à événements discrets en phase de conception pour évaluer conjointement les propriétés structurelles (commandabilité, observabilité,etc) et leurs paramètres de sûreté de fonctionnement. L’analyse de propriétés structurelles des systèmes continus repose sur la théorie des graphes s’appuyant sur la connaissance des phénomènes physiques mis en jeu. L’analyse des paramètres de sûreté de fonctionnement s’appuie d’une part sur la connaissance des relations liants les composants, leur état de fonctionnement et la causalité physique et d’autre part sur une modélisation par un formalisme dédié aux systèmes à événements discrets. La démarche est illustrée sur un cas d’étude.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
