Study On Operation Organization Related Questions Of Sea-rail Combined Transport In Guangzhou Railway Group

With the continued decline in rail freight, Guangzhou Railway Group should expand new channels in the transportation market as soon as possible, so as to improve the efficiency of the group. It has more seaports in nationwide, sea-rail combined transport is an important breakthrough for developing freight of Guangzhou Railway Group in the new situation. Sea-rail combined station plays a bridging role in the overall transportation, so it is very necessary to study on operation management pattern, the division of stations and process of sea-rail combined station in the group. This paper made it as follows:Firstly, it analyzes systematically two kinds of operation management modes in the current sea-rail combined stations, on the basis of the analysis of their own adaptability and the influence factors for mode selection. Besides, it puts forward the operation management modes to adapt to the sea-rail combined stations in Guangzhou and Shenzhen ports;Then, it analyzes quantitatively the rational division of sea-rail combined stations in Guangzhou Railway Group. This paper establishes the optimization model of the shippers to pay minimal expenses as objection, and obtains the station division scheme. In the model, the goods in each station assigned amount are set as decision variables. Constraints are as follows:transport capacity of the pending division stations, handling ability and yard capacity, line capacity, freight volume of port by railway.Finally, on the basis of the proposed operation management mode above, it optimizes the process of sea-rail combined station and describes the safeguards for developing sea-rail combined transport.
