Study on Optimized Organization Scheme for Through Heavy Haul Trains Based on Changing-for-weight

For the loading points the coal minerals and other bulk cargo,the coexisted heavy haul railway and common railway causes the diversity in organization scheme for through heavy haul trains,the optimization method is also different from the normal.First,this paper analyzed various combination programs compiled at the loading points,and their cost in the heavy haul transportation system.Then,established a 0-1 non-linear programming model based on the circumstance of endpoint-thang-for-weight.Considering the large scale of the model,and hard to solve by traditional mathematical methods,this paper designed a solution method based on genetic algorithm.The result shows that this algorithm is an effective way to solve the problem with optimized organization scheme for through heavy haul trains from the loading points.
