System Modeling And Simulation Of Railway Container Node Station Based On EM-Plant

At present, the foreign railway container-handling station has already developed towards a large-scaled, specialized and modernized mode. To adapt to the characteristics of the relatively concentrated railway container traffic volume and to improve the efficiency of railway container traffic volume, we should speed up the adjustment of the overall arrangement of the whole railway container-handling stations, and strengthen the construction of railway container node station build, finally to meet the needs of multi-model transportation and the development need of modem logistics. In order to keep pace with the quick development of railway container traffic in the "Long-term program for the railway network" deliberated on Jan.21.2004.The State Department have put forward a program to optimize the distribution of all railway container -handling stations, and to set up 18 railway container node station.Railway container node station is a complex random service system. The actual operation shows discrete and random characteristics under the influence of random factor. Railway container node station is a kind of discrete affairs dynamic state system of typical model, this decides the difficulty that the railway container node station plans and designs. In this paper, according to data information of the railway container node station, the system simulation model is established by using eM-Plant simulation platform software. Take some node station as an example to verify accuracy of the model, this railway container node station is studied by using the simulation model, and other node stations can modify the model and apply on the base of the model. By the simulation, and decision-makers of the node station can reach a decision. In this paper, the research contents mainly have a few aspects as follows.(1)On the basis of the analysis existence question of the railway container node station, make sure the construction planning requirements of railway container node station in china. Research situation of the railway container node station at home and abroad currently is analyzed, using system simulation technology, container node station is analyzed.(2)On analysis and intercomparison to the common loading/unloading machinery, the selection of the loading/unloading machinery of node station is studied, then make sure which loading/unloading machinery is suitable for the node station. The under span layout of the rail-mounted gantry crane is researched by using eM-Plant simulation platform software, and the superior layout is make sure.(3)According to the nature and function of container node station, the technological process and the several random events of the railway container yard loading/ unloading system is analyzed, and reasonable work flow and random event distribution are make sure. The simulation model process is established and the model structure module is divided by using eM-Plant simulation platform software, and the simulation model of railway container node station is designed.(4)On finishing the data of some railway container node station in 2000, the correctness of the simulation model process is verified by using this data as input data, this node station is evaluated, and the existent problem of the node station in 2000 is found.(5)On forecast of transportation volume of this node station in 2010, the simulation model is run on analysis the data, and The simulation shows whether the equipments quantity and ratio is reasonable or not.
