Research On Simulation Of Motor Train-set Operating Based On The Train Plan

The motor train-set is one of the most important locomotive equipments in the dedicated passenger line. The rationality of the operating and maintaining of motor train-sets directly influences the product quality and efficiency of the dedicated passenger line. It is not only a key index of the evaluation of train plan but also a reference of developing the follow-up transport organization plans. As the transport organization plans are organized in stages, the situation of motor train-set operating and maintaining only can be gotten after the completion of timetable and train-set scheduling. Thus it can't provide timely data for the train plan evaluation and guide follow-up transport organization plans either. Therefore this paper would research on a rapid access to reach the situation of motor train-set operating and maintaining when the train plan is given.This paper proposed a method which firstly made the train running scheme and then the train-set scheduling according to the analysis of practical problem and advantages of the train running scheme. The paper first defined the borders of the train running scheme, and then established a corresponding mathematical model based on the analysis of related factors. The algorithm of the train running scheme was also designed and implemented by means of artificial simulation. After that, the motor train-set scheduling problem can be transformed into TSP problem, and the mathematical model can be established. As to the algorithm, it selected a way which was composed of meta-heuristics and Simulated Annealing. At last the paper designed and implemented simulation system which can weave and display the train running scheme and motor train-set scheduling, be manually adjusted, and count indexes. In the paper, the simulation system provided the corresponding data for the train plan evaluation and follow-up transport organization plans by importing the Beijing-Shanghai line's train plan. It effectively solved the problem and also the availability of methods and system was proved. So the conclusion of this paper has both theoretical and practical significance.
