A Study on the Optimization of Maritime Transportation Network by using Complex Networks

Abstract

The amount of cargo transportation increases rapidly, and the maritime transportation network has been complicated in recent years. Therefore, the rationalization and efficiency improvement of cargo transportation are required in the international maritime transportation. In this study, a maritime transportation networks are examined by using complex networks and new planning method of maritime transportation networks in consideration of the characteristics of networks is proposed.
In order to realize these, planning of maritime transportation networks is formulated as a multi objective optimization problem considering transportation costs and representative values of the network. Optimization results are compared with the other networks, i.e. Kurokawa network model, and the optimized network models only considering transportation costs and so on. As a result, the effectiveness of the proposed method is shown.
