| Author | Cheng-Chang Lin, Jin-Lin Wu |
| Summary | Time-definte common carriers announce tariff and provide time-guranteed delivery service for small shipment shippers. The line-haul operational planning determines freight routes, balanced trailer movements, and feeder routes and schedules. Even though they are mutually interactive, in practice, they are solved sequencially. In this research, we proposed an integrated model for the line-haul operational planning problem. It simultenously determines freight paths, balanced trailer network, and feeder routes and schedules while meeting the service commitment and operational restrictions, so that the total operating cost keeps to the minimum. We decomposed the problem into two sub-problems, freight routing and trailer-balanced feeder routing and scheduling, with a built-in iterative scheme to realize their mutual impacts. We used the third largest common carrier in Taiwan for numerical testing. The result shows that the integrated model results a small feeder fleet rather than solving two sub-problems sequentially. Furthermore, the on-duty strategy outperforms the load utilization strategy in the selection of feeder schedules. |
