This paper deals with a cost minimization problem of oceangoing carriers on a large-scale network of international maritime container shipping industry, in order to measure impact of port policies for each country including Japan. Concretely, the authors develop a model to decide ports to call and size of containership in each route by ocean-going carrier group, with consideration of construction of deeper berths to deal with enlargement of containership, decrease of various port charges per cargo by attracting cargos into one port, and congestion by exceeding aggregation.
The developed model is applied to the actual large-scale international maritime container shipping network in Eastern Asia. The performance of the model developed is validated. Also, the sensitivity of the model output is confirmed from the viewpoints of economy and diseconomy of scale included in the model.
