Abstract
The purpose of this paper is to integrate Sustainable Transportation Network Design through the application of transportation, transshipment, and vehicle routing optimization models. A mixed-method research approach combining qualitative and quantitative methods was adopted with a in the distribution system of Moha Soft Drink S.C. The database consists of 10 interviews and 49 documents, the current distribution system is largely experience based and lacks integrated optimization mechanisms. The application of optimization models highly reduced transportation cost, improved vehicle utilization, minimized unnecessary travel distance, and enhanced route efficiency. Furthermore, the optimized distribution network improved sustainability through reduced fuel consumption and lower transportation related environmental impact. The optimization network reduces total transportation cost from 23,712,296 to 4,292,000 then 623,868.70 then finally to 466,093.44 and decreased total carbon emission by 285.21kg per kg. The findings contribute to theory development at the intersection of transportation, transshipment, and vehicle routing models provides an effective framework for designing sustainable logistics systems within the beverage industry. By diffusing knowledge regarding available remedies, the study contributes to improving sustainability effectiveness, thereby fostering both practical and theoretical insights into supply chain optimization and sustainable transportation management. This research highlights the criticality of Sustainable Transportation Network Design .The sustainable transportation network effect on Using Transportation, Transshipment, and Vehicle Routing Models reduced fuel consumption and lower transportation related environmental impact.
