Abstract
In a context of economic volatility, multiple crises, and growing environmental concerns, the optimization of physical and financial flows has become imperative for businesses.In a classical Inventory Routing Problem (IRP), only the physical flow of goods is considered.This paper introduces a link between a two-echelon Inventory Routing Problem and the financial flows of the Working Capital Requirement, where the products are dispatched from warehouses to fulfill customer demand.We propose a two Echelon Inventory Routing Problem under Working Capital Requirement (2E-IRP-WCR) model which allows us to evaluate the integration of physical and financial flows so as to further reduce the total cost, where the total cost consisting of ordering and inventory costs, transportation costs and financial costs.Numerical tests, established for multi-suppliers, multi-warehouses, multi-customers, single-product and finite capacity cases, are presented to demonstrate the pertinence of our approach.

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
