This study tackles the issue of truck driver shortages by proposing an optimization model for scheduling trucks on circular transport routes to ensure evenly spaced arrivals at factories. Given the limited storage space in Japanese factories and the steady consumption rate of parts, efficient scheduling is crucial. The model employs Mixed Integer Second-Order Cone Programming (MISOCP) and local search to achieve this. Numerical experiments demonstrate that the proposed method significantly improves scheduling efficiency, meeting practical target values. The findings confirm the model’s utility in addressing logistical challenges and enhancing operational efficiency in the face of driver shortages and regulatory constraints.
