Optimization Model for Assignment of Wagon Flows in Railway Network

  • The current mathematical models for wagon flow routing were amended based on analyzing their limitations and considering the wagon flow reorganization so as to choose the route of wagon flows correctly.Three groups of 0-1 variables were set,and models for choosing the route of wagon flows were proposed on the basis of the concrete practice of Chinese railway to minimize the total cost of wagon flows spent on technical stations and running on railway lines.In the proposed model,the situation that the OD(origin-destination) wagon flow can not be fully assigned is considered,and the defect of ignoring the wagon flow reorganization is overcome to avoid inaccurately choosing the route of wagon flows.As a result,the wagon flow assignment and reorganization corresponding to Chinese reality can be got.
