Abstract
We consider an industrial application encountered in the Moroccan context that involves the production and distribution of bottled water. Our industrial partner owns one plant from which all requests are delivered in direct shipments and usually full truckloads to the customers (a set of regional depots and wholesalers). We must take into account the production, the delivery requirements, multiple products, and inventory levels. The objective is to minimise the sum of the production, transportation, and inventory costs. We propose a mixed integer linear program for a variant of the multi-vehicle, multi-product production routing problem. Experiments have been conducted using CPLEX 12.3.0, and almost all instances were solved with a reasonable optimality gap. The results show that significant savings can be obtained by using our approach with respect to the current company practice.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
