The Port Layout Of The Game In The Competition Analysis And Optimization

This research is based on the internal economic rule of waterway that is the benign circulation of interaction among port authority, carrier and shipper. Aiming at getting the reasonable layouts of hub and spoke ports under more and more keen competition, this thesis presents a reliable mathematical model to forecast containers flow and the amount of calling vessels. Therefore, we can get the layouts of hub and spoke ports. This model provides a reliable rule for ports layout and its future development planning. Firstly, trend of development of container ports is described in this thesis. Then, some economic theory in port planning, mathematical methods in optimization of transportation networks, and relevant research about application of game theory on transportation are concluded. The principle of competition in port market is analyzed and the interactive relationship among port authority, carrier and shipper is deeply studied. The market model of competition of container ports is therefore got. Secondly, according to the behaviors of players in container transportation game, carrier s and shipper?s optimization objectives is respectively set up. Then, simulating the process of decision by carrier and shipper, we present a carrier梥hipper game model for optimization of transportation networks. Genetic Algorithms is applied to solve this large scale bi條evel constrained combined optimization model. Finally, the game model is tested in real梬orld optimization of container transportation networks around Bohai district. The patterns of cargo flow and the service frequency of calling vessels is got. The result of possible competition between Dalian Port, Tianjin Port and Qingdao Port shows reasonable. We also take Dalian Port as example to analyze its future planning of lines layouts.
