Optimization of Coca-Cola Product Distribution Routes at PT. Graha Prima Mentari Medan With Ant Colony Optimization
Bibliographic record
Abstract
PT Graha Prima Mentari is a company engaged in the service sector, namely as the official distributor of Coca-Cola. PT. Graha Prima Mentari has Distribution Centers spread across various cities including those located in the cities of Cirebon, Indramayu, Tasikmalaya, Pekanbaru, Medan, Denpasar, Rembang and others. For branches in the city of Medan PT. Graha Prima Mentari is located at Jalan Gatot Subroto KM 6.7 No. 100 Fields. PT. Graha Prima Mentari has 13 transportation cars that operate from Monday to Saturday and serve 6 areas, namely Medan Barat, Medan Sunggal, Medan Helvetia, Medan Selayang, Medan Tuntungan and Medan Petisah. The problem that occurs is that the company has not determined the optimal route which results in additional costs for the distribution of goods. This study aims to minimize the distance by using the ant colony optimization method. The result obtained is that the distribution distance is reduced by 52 km from the previous distance of 93.1 km to 41.1 km and saves distribution costs of Rp.49,000.

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.
