Research on Simulation Model of Train Operation Plan
摘要
Abstract
In order to simulate the implementation process of train operation plan with the help of computer virtual technology,the simulation model describing train operation environment,state and rules was built for developing train operation simulation platform.Combining with the characteristics of railway transportation organization,the train was defined to be individual token,the railway network environment and train operation information were defined to be places which were expressed by color sets,the location transformation and operation information transfer of train were realized by defining a variety of transitions,and the running of system was driven by defining an increasing variable named global clock with the help of improved Petri nets.The train operation simulation model was based on the thought of component combination,considering the bidirectional operation characteristics of line and the random disturbance in the process of train running at the same time.The simulation framework corresponding to train operation environment and train operation rules could be generated rapidly according to the train operation plan needed simulation and railway network related data.After the initialization of each static parameter according to relevant data,the train operation plan could be simulated according to regional scope and time required.Simulation examples show that the model is intuitive and easy to program,and simulation results are basically consistent with objective reality.关键词
