In the development of the national logistics system, Indonesian’s government planned to build two international ports in Kuala Tanjung and Bitung to support the increasing volume of export and import containers. This development aims to make Indonesia no longer depend on the ports of neighboring countries. Currently, the international cargos are shipped from Indonesian ports to Port of Singapore as an international hub applying hub and spoke network concept. According to the “Sea Tollway” program, vessels with a fixed schedule are assigned to serve these networks. The long shipping routes followed by several problems, including vessel inefficiency caused by demand imbalance between each port. These imbalances are the effect of trade disparities between west and east region of Indonesia. For route with these characteristics, the network and fleet planning are important factors to improve efficiency that has a direct impact on minimizing shipping cost. In this research, we analyze the fleet planning for routes serving international container shipping from six main domestic and two international hub ports in Indonesia, which are Belawan, Tanjung Priok, Tanjung Perak, Banjarmasin, Makassar, Sorong, Kuala Tanjung, and Bitung. We developed the linear programming model modified from the Feeder Network Design Problem (FNDP). To choose the right vessel size for the routes, we added utilization as a factor that must be considered in the model. Finally, by solving the model we get the optimal vessel size and quantity for each route.
