Continuation Program Optimization Of Train-Sets In The Passenger Dedicated Lines Station

In the station with train departing and arriving on the passenger special line, the train-set continue is an important daily technical work, and the optimization of the continue plan can effectively improve the efficiency of using the departure line and train-set. Based on the existing passenger scale, to enhance the using efficiency of departure line can release the station ability to adapt to the passenger growth; and in condition of certain transport task, to increase the using efficiency of train-set can accelerate its turnover and reduce the number being needed. The simulation of the station can not only simulate the existing daily work process dynamically and intuitively, test the feasibility of train diagram and provide feedback information, but also can simulate the station unbuilt, after repeated simulation experiments, the scale and form of the station can be determined basically.For the optimization problem of train-set continue, the existing researches were mainly from the angle of train-set using which had achieved a lot, but less of them were from the angle of station. Based on the existing researches, this paper researched this problem from the angle of station organization work, combined with the scheme generation of. train-set continue, the using arrangement of departure line and throat route, and finally showed the achievements by a dynamic example, which includes:(1) This paper analyzed the influence factors and the possible work processes, so as to determine the time standard of train-set continue in station.(2) A multiple objective programming model was described which limited the boundary and applicable range by assumptions, the two objective functions were the maximum reception and departure of trains and the minimum invalid residence time in station, and the constraint conditions were used to guarantee the feasibility of continue plan.(3) This paper created distribution network of equipment period, defined related algorithm of network, and designed the transform and update method based on the algorithm, so as to reflect the whole operation processes of train with different properties and to ensure the feasibility of work arrangement.(4) Based on the above network and method, the dedicated algorithm of the model was designed.(5) On basis of the research achievements, with specific related data, this paper simulated all the technical operations in station by computer programming technology, so as to test and verify the theory. All of these aspects of the research had made corresponding research achievements, and provided a theoretical support and realization method for the development of the simulation system. Through the development of specific example, the feasibility of this method was proved.
