Application of Goal Programming in Railway Heavy Haul Transportation

Goal programming was applied to obtain the heavy haul train operation plan. Four grades of priority are defined in the goal programming model according to the practices of heavy haul transportation in China railways. The 1st priority prescribes the prescriptive transportation volume index,and the 2nd to 4th priorities depend on the capacity of the railway line and the constraints of available locomotives and vehicles. The goal programming model for Datong-Qinhuangdao railway line was derived,and its parameters were defined. The model was solved using the simplex method. The calculation results are the obtained train operation plans meeting the demands of practical heavy haul transportation.
