摘要

This paper proposes a new reinforcement learning method for train marshaling. In the proposed method, marshaling plans for freight cars in a train are generated based on the processing time. In order to evaluate the processing time, the total transfer distance of a locomotive and the total movement counts of freight cars are simultaneously considered. Moreover, by grouping freight cars that have the same destination, candidates of the desired arrangement of the outbound train is extended. This feature is considered in the learning algorithm, so that the total processing time is reduced. Then, the order of movements of freight cars, the position for each removed car, the layout of groups in a train, the arrangement of cars in a group and the number of cars to be moved are simultaneously optimized to achieve minimization of the total processing time for obtaining the desired arrangement of freight cars for an outbound train. Initially, freight cars are located in a freight yard by the random layout, and they are moved and lined into a main track in a certain desired order in order to assemble an out bound train. In computer simulations, a perfoemance of the proposed method is compared to that of the method based on the movement counts of freight cars and of the method based on the transfer distance of locomotive.
