Abstract: Maritime cabotage legislations is a system related to the coastal shipping, which reserved for domestic ships or open to foreign ships is a problem. Port congestion mainly occurs on the hub shipping network. An optimization problem of hub-and-spoke shipping network with maritime cabotage legislations and port congestion is proposed in the paper. Based on the problem, a small-scaled integer programming model is formulated with minimum total transportation cost. Experiments on the 10 ports selected from the major areas of Asia-Europe-Oceania shipping network show that it is reasonable to determine the hub position by considering the economy scale of cargo flows between the hub ports as well as the congestion costs. When costal shipping allowed, the foreign shipping companies can change container transshipment ports. The proposed model can be solved efficiently by CPLEX.
