Abstract

fetched live from OpenAlex

De afgelopen jaren is er een sterke stijging geweest omtrent e-commerce, met name de last mile delivery, waarbij consumenten meer en meer de producten online aankopen. Er is dan ook een stijging van bestellingen van kleinere hoeveelheden. Het begrip “Vandaag besteld is morgen in huis” maakt het e-commerce gebeuren alleen maar complexer voor de logistiek. Bij het online aankopen hebben klanten bepaalde verwachtingen zoals een hoog service niveau en lagere verzendkosten of retourkosten. De snelle levering die aangeboden wordt en de verwachtingen van de klant hebben een grote impact op kosten en milieu. \nUit de bovenstaande probleemstelling kan in deze masterproef bijgevolg de volgende centrale onderzoeksvraag onderzocht worden: “Welke innovatieve oplossingen bestaan er in Europa om de druk van e-commerce leveringen aan consumenten terug te dringen in de verschillende gebieden?” Om een antwoord te formuleren op deze onderzoeksvraag, werd er eerst een literatuurstudie en vervolgens een empirische studie uitgevoerd.

Not 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.
