Optimal model of daily freight plan of railway sub-administration dispatch based on benefit mechanism

In order to get the maximum transportation benefit under the limited traffic resources, an optimal model of daily freight plans of railway sub-administration dispatch was established based on the benefit mechanism and the exact mathematics descriptions of traffic restrictions such as capability of stations, supply of empty vehicles, capability of limited nodes and capacity of dividing stations. In this optimal model, the object function is to get the maximum transportation benefit, and the constraint conditions are the traffic restrictions.
