| Title | Route Selection and Fleet Deployment for a Container Liner |
|---|---|
| Author | Hua-An Lu, Yu-Chang Hsu |
| Summary | A container liner needs to provide shippers a long-term and stable route service plan to achieve a fixed market share and further to develop more new shipping markets. Such service routes are always designed depending on the experience of planners, the estimation of demands, geographical positions of calling harbors, and some practices of navigation in the process of practical planning. We assume that more candidate routes are given followed above in this research. A mathematical model maximized the profit of the carrier is formulated to decide which routes should be selected and how many and which kind of vessels should be deployed on them. We obtained not only the results of route selection and fleet deployment but also carried containers allocation among different port pairs. Besides, some constraints of service frequencies can be optionally taken into this model consideration as well. Test results show the correctness of model applied. We further relaxed the integrality of container variables at solving this mixed integer programming for reducing much time consumed of calculation. Results of sensitivity analyses by adding optional frequency constraints on certain demands reflect that the more vessels are required, the more the profit is lost. |
