Study On The Method Of Preparation Of EMU Scheduling Plan

High speed EMU is the most important equipment of Chinese existing railway,high-speed railway.EMU’s purchase, repair costs, occupies a large proportion in the investment in railway infrastructure construction in China.EMU Operation Plan is one of the transport production daily work plan,Whether it is Efficient and suitable,Directly affects the railway investment and operating costs.With China’s high-speed rail operation mileage increasing and continuous usage of high speed EMU,How to develop fast, efficient with the actual production of the motor train set scheduling has become a serious problem.Based on the previous research at home and abroad, combined with actual production situation as the premise, This paper analyzes the current probelms in motor train set scheduling, elaborated factors of motor train set scheduling theory basis and influence. the EMU Operation planning is transformed into MTSP problem with distance constraints,with specific analysis of the characteristics of the MTSP problem itself.In this paper, combined with the high-speed railway gradually into a network of domestic situation,we established the motor train set scheduling mathematical model with goals that EMU could be used least number and the most balanced,based on a precondition for multi car and Multi base,not to be used the fixed section.In this paper, We analysisd the difficulties of this model in the technology and algorithm and described in detail how to use genetic algorithm for solving such special MTSP problems. Using the daily Shanghai High-speed Rail operation plan as an example, the results show that the model and algorithm has certain applicability.The research work and conclusion give theoretical support of EMU Operation Management Mode and efficiency-improving.It has the reference significance to solve the problem of how to use the heuristic algorithm.
