【摘要】：沿海运输权制度是沿海运输是否保留给本国船舶或者向外国籍船舶开放的制度。港口拥堵主要发生在海运网络的枢纽港上。通过考虑沿海运输权和港口拥堵对轴辐式海运网络加以优化,以海运网络内货物运输总成本最小化为目标函数,构建一个小规模整数规划模型。从欧亚航线覆盖的主要地区中选取10个港口组成海运网络进行算例分析,并使用CPLEX软件进行求解,研究结果表明,通过考虑枢纽港间货物运输的规模经济效应和产生的拥堵成本,可合理地确定枢纽港的位置;若允许沿海捎带,外资航运企业将会改变货物中转的港口。
[Abstract]:The system of coastal transport right is whether the coastal transport is reserved for domestic vessels or open to foreign vessels. Port congestion mainly occurs in the hub port of maritime network. A small scale integer programming model is constructed by considering the coastal transport rights and port congestion to optimize the axle-spoke marine network and to minimize the total cost of freight transportation in the maritime network. From the main areas covered by Eurasia route, 10 ports are selected to form a maritime transportation network for example analysis, and the solution is carried out by using CPLEX software. The research results show that the seaborne network is composed of 10 seaborne ports. The location of the hub port can be reasonably determined by considering the economies of scale and the congestion cost of the cargo transportation between the hubs. If the coastal piggyback is allowed, the foreign shipping enterprises will change the port of transit of goods.
