The Research On Optimization Method Of EMUs Plan

With the vigorous development of China’s high-speed railway, the EMU is widely used in railway operations, how to arrange the use of the EMU is to improve the key to the efficiency of railway operations. The use of EMU related to the travel time of the EMU on the railway, the contents of the EMU play trips through the station, departure time and arrival time, walk the line path and routine testing and maintenance. Because of the high buying cost and maintenance costs, the Motor Tran-sets Scheduling aims at using the train rationally to reduce the total number of the train and improve the train using efficiency, and also it is of great significance to the operation management of the dedicated passenger traffic line. Recently, the operation management of the dedicated passenger traffic line and the use of the motor train-sets of our country are still placed in the exploring stage, so we cannot just simply use their modes for reference. So it is ought to combine with our own actual facts to do research.This article is related to the constraints and to achieve the purpose of optimizing the combination of EMUs train set plan will move into the traveling salesman problem TSP. Take full account of the connection conditions and maintenance conditions based on the design of the corresponding mathematical model. Algorithm to solve the problem of EMUs analysis and comparison of the advantages and disadvantages of the various algorithms, the final account, choose the simulated annealing algorithm as the algorithm to solve the problem.
