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.
