Impact of Quality Grading and Uncertainty on Recovery Behaviour in a Remanufacturing Environment
Bibliographic record
Abstract
This research considers a remanufacturing enterprise that constitutes a stage in a closed loop supply chain. Each returned item is precisely tested and assigned a quality grade between zero and a hundred. Consequently, acceptance to the facility, acquisition price and remanufacturing cost are all quality dependants. The research implements the newsvendor modeling techniques to model the system when a single remanufacturing facility satisfies a single market's demand or when multiple remanufacturing facilities satisfy multiple markets' demand. Thus, non-linear programming or mixed integer non- linear programming models are proposed to maximize the total profit by selecting facilities to operate, optimal minimum quality to accept into each operating facility and market's demand to satisfy from each operating facility. Returns' quality is considered to be stochastic, while markets' demand could be either stochastic or deterministic. The impact of changing returns, quality and demand uncertainties, and transportation cost on remanufacturing systems are studied.

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.
