Research Of The Two-stage Scheduling Optimization Of Branch Of Container Transportation Routes By Two Type Of Ship In Pearl River

As the technological advances and the world are getting closer and closer, the shipping industry is beginning to develop and is becoming increasingly important in economic activity. The At the same time, the container transport industry and the traditional ship transport than the advantages of greater, more convenient and flexible,but also with the world trade growth and rapid development, and gradually mature.Shipping companies in order to reduce costs, access to economies of scale, the construction of the ship is growing. And large container ships due to the ship size, high tonnage, can not be anchored to small ports, and began to shaft-type container transport mode. Pearl River Delta in China's developed Guangdong Province, the economic hinterland is very large, densely populated, and is the Pearl River in China's estuary. In addition, the Pearl River Delta region has a huge transport team, a total of more than 350 companies in the Pearl River Delta region has a shipping business, due to the complex geographical environment in the Pearl River Delta region and the size of the port, a good form of the axis of the Transport network structure. With the development of container shafts, trunk transport and feeder transport began to distinguish, and because of the reasons for the physical and geographical environment, as well as the reasons for the market, the shipping company in the development of feeder transport routes, as well as ship scheduling program encountered various problems The In view of this, to help ship companies to develop a ship scheduling plan to determine the ship running routes, the shipping companies need to deal with the difficulties.First, the shipping market and background are introduced, and then the theory of container transportation is discussed. The advantages and disadvantages of container transportation in the Pearl River Delta region are analyzed, and the theory of ship speed optimization is analyzed. Speed optimization model, and for the market information is volatile, proposed in the case of speed optimization of the two-stage dynamic scheduling model. Through the analysis of the 28 ports in the Pearl River Delta region,it can be proved that the model established in this paper is reasonable and can help the shipping enterprises to carry out the ship scheduling more rationally.
