Optimization of Set Assignment of Passenger Train in Uncertain Sections of Railway
CUI Shanshan
Abstract：Through the analysis of application of the current passenger train set ,this article puts forward that the application of the train set assignment can increase its efficiency and decrease the connecting time of the train set assignment at the station .The paper searches for the initially feasible train number connection duty strings by constructing train number connection network diagram , establishes the model of the train set assignment in uncertain sections ,in which each train number is covered and only once as the constraint condition , and the minimum number of the train set assignment in use is the objective function , and finally adopts the genetic algorithm to solve the problem .The model is used to verify the operation conditions of passenger trains at some large passenger stations of four areas such as Beijing ,Wuhan ,Guangzhou and Shanghai .The results show that the connecting time of the train set assignment decreases and the train set assignment is less used in quantities .
