Study On Scheme For Storage Yard Layout Of Container Node Station

At present, with the rapid growth of rail freight traffic, the development of container transportation is also extremely fast. At the same time, however, there are some problems in the process of rapid development of container transportation, such as the business of container station is too excessive and the time of handling cargo is too long, the quality of service cannot satisfy the requirements of modern logistics. In order to meet the demand of the container logistics services'rapid growth, many container terminals are carrying a lot of renovation and expanding projects. Therefore, the operation planning and the freight yard layout of the terminal becomes an extremely important issue.Combined with the current development of railway container transportation, the paper researched the method of storage yard layout for container node station. The contents of this paper are showed as follows:(1)Firstly, the paper had a comprehensive and general understanding on the research status of the related subjects by reading extensively a large number of literatures. Based on this, the clear background and the significance of the paper was given, at the same time, the research contents were determined.(2)Then based on the above thesis, the paper analyzed the current status of the development of Chengdu railway container transportation and introduced the natural state of Chengdu railway container node station. According to the present status of Chengdu, the prospects of development of the Chengdu railway container transportation were introduced.(3)According to the present situation of railway container transportation, the factors which affects the containerized traffic were analyzed, then, several forecasting methods were introduced briefly, and the gray model was introduced chiefly. At the same time, based on the analysis of economic and transport structures of Chengdu, the related data was collected, then the volume of the containerized traffic in Chengdu container node station was forecasted by using the gray model, the volume in 2020 was given too.(4)In this paper, the problem about the selection of container loading and unloading equipments was researched, and the container loading and unloading equipments were evaluated by using AHP. Finally, the reasonable loading and unloading equipment was given.(5)The paper analyzed the storage yard layout of Chengdu container node station by combing the operational contents, then the number of the loading and unloading equipments and the scale of the main container areas were calculated, the length of main lines was given.(6)The mathematical model of the freight yard was established by using computer, then the change of various volume was analyzed by using the simulation method. When the loading and unloading equipment was rail container gantry crane, the optimal schedule of the freight yard layout was given by using this model.
