Slotting Optimization for Railway Freight Yard Based on GeneticAlgorithm

摘要

Freight yard is the basic production unit of railway freight transportation. The slotting optimization in it is significant to increase the utilization of freight site, reduce the operating cost of freight yard and enhance the operating benefits of the railway transportation enterprise. This paper analyzes major factors influencing the slotting optimization, and puts forward an optimized mathematical model which is based on the principle of minimizing the time to store and fetch goods. Moreover, the major factors are transformed with penalty-function; meanwhile, improved genetic algorithm is taken as the method. Finally, this paper adopts MATLAB GA Toolbox to carry out the visualized solution for the optimization, the results of which indicate that the slotting optimization model can well enhance the efficiency of storing and fetching goods, and realize the aim of minimizing the cost in the freight yard.
