Abstract: Regard the total cost minimum of the carrying loaded and empty wagon flow as the objective, follow the principle of wagon-flow no separation and continue merging, consider railway line capacity restrain, collaborative optimization model is constructed integrating loaded wagon transportation and empty distribution of many categories in railway network. The model overcomes the separation defect between the traditional loaded wagon carrying optimization and empty distribution optimization. The result shows that the model is effective and feasibility.
