Operations optimization of placing-in and taking-out of wagons of tree-shaped special lines
In order to efficiently prepare the dendritic special line pickup and delivery scheme,considering the number of locomotives,the traction capacity of locomotives,and the sequence of shifting operation nodes,an opti-mization model with pickup and delivery operation time as the goal is set up;and then,according to the nature of the operation,an improved genetic algorithm combining genetic algorithm and large-scale neighborhood search al-gorithm is designed to solve the model.Taking the pickup and delivery operation of a railroad station as an exam-ple,the model is solved to verify the validity of the model algorithm,and the results show that:the established model solving scheme is in line with the reality,and the designed improved GA algorithm can solve the model quickly and efficiently,which verifies the validity of the improved algorithm.
