摘要：

With comprehensive consideration of the wagon-flow route selection and the formation scheme formulation, the optimization problem of the mixed formation of multi-block and single-block freight trains with the large running wagon-flow route selection of the trunk line in railway network is studied, and the model with second-order progressive structure and its solution strategy are constructed. On the basis of constructing an optimization model for single-block train formation embedded in wagon-flow route selection, aiming at maximizing the saving of wagon-hour by replacing the original single-block train operation scheme with the multi-block train operation scheme, the optimization model for multi-block train formation based on the combination and sorting of single-block train schemes is further established. In the solution process, three updates are made to optimize the single-block train operation scheme firstly. Then, the operation schemes of union and linking multi-block trains are respectively generated through the combination and sorting. Finally, the most optimal operation scheme of multi-block train is screened out according to the principle of the train unit uniqueness and the wagon-hour saving. Relying on the designed experimental scenario of the main corridor in Chinese central railway network, the effectiveness of the model and the solution strategy is verified. The results show that the most optimal operation scheme of single-block train operates 17 trains and takes 11,560 wagon- hours after considering the wagon-flow route selection. The further optimized scheme for the mixed formation of multi-block and single-block freight trains can reduce 1 train and save 582. 5 wagon-hours. The model and solution strategy can effectively solve the optimization problem for the mixed formation of multi-block and single_ block trains considering wagon-flow route selection. © 2023 Chinese Academy of Railway Sciences.
