Study On Station Operation Sim-system Of Passenger Dedicated Line

The station of passenger dedicated line is the links which connect the society market and passenger dedicated line system, the node and center of passenger dedicated line network. Station operated orderly, effective, is the key of full utilize the station facility, it also affect the station capacity indirectly. In the environment of the vigorously construction of passenger dedicated line in China, it is necessary to do the study on Station operation organization, influence between station facility and capacity.Simulation of railway transportation system is to design or establish a computer model of one railway system to replace the actual system based on simulation model, to analyse and research the dynamic action of the certain system under certain situation, it has the features of low cost, low risk, high speed, and convenient collection of information. Based on the railway transportation operation organization theory, optimization theory, system engineering, system simulation theory, computer technology, the paper did a systematic study on Station Operation Sim-system of passenger dedicated line. That includes several aspects as follow:(1) Summarized the development status of railway transportation simulation soft, studied the application of system simulation theory in transportation system simulation; analyzed the principle, method and features of the transportation system simulation, include its step, validity test method, then defined the research scope of this paper.(2) Take initial station for example, analyzed the technological processes and features of station operation, analyzed the method of station operation simulation, established the station operation simulation model based on the discrete event system simulation theory from a microcosmic view, then study the entity and its attribute, event, active, process, state in detail, proposed the system simulation strategy.(3) Analyzed the station operation simulation algorithm, put forward the requirement of the simulation algorithm for the certain system, based on the transportation operation organization, optimization theory, studied the high speed optimized algorithm of throat route arranging and optimized scheme of application of arrival-departure lines.(4) Based on the theory, model, algorithm study of this paper, the author developed the Station Operation visual Sim-system (SOS) of passenger dedicated line.(5) Analyzed the factors which affect the station capacity of passenger dedicated line, proposed a new method to calculate the station capacity by the SOS, studied the influence between station facility and capacity such as throat layout, arrival-departure lines quantity. With SOS, the paper studied the relationship between the arrival-departure lines quantity and the station capacity.The paper did a system study on the Station Operation Sim-system form theory to application, expect to provide the theoretical support and suggestion in yard designing and reference database for further operation, and lay a foundation for further study on railway transportation system simulation.
