An AHP Based Approach for Multi-echelon Inventory System Selection: Case of Distribution Systems
Bibliographic record
Abstract
Nowadays, inventory management is becoming more difficult as supply chains are complex and involve many facilities for different stages. The multi-echelon inventory management permits to the supply chains to be more competitive by an efficient control of inventories and a high responsiveness of the whole system. As there is no single exact inventory management policy, and there is a multitude of multi-level inventory models, the selection of the most suitable alternative is not easy. There's few previous research done concerning the selection phase of a multi-echelon inventory system in our knowledge. In this paper, we try to contribute in the literature by using the Analytic Hierarchy Process (AHP), a multi-criteria decision making method (MCDM), that helps a Decision Maker (DM) to choose and select the appropriate multi-echelon inventory system. We focus in this research work on the case of distribution inventory systems. We apply this framework to the Moroccan public pharmaceutical supply chain.

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.
