A Reinforcement Learning System for Transfer Scheduling of Freight Cars in a Train
نویسنده
چکیده
In this paper, a Q-Learning method for trasfer scheduling of freight cars in a train is proposed. In the proposed method, the number of freight-movements in order to line freights in the desired order is reflected by evaluation value for each pair of freight-layout and removal-destination at a freight yard. The best transfer scheduling can be derived by selecting the removal-action of freight that has the best evaluation value at each freight-layout.

A New Reinforcement Learning Method for Train Marshaling Based on the Transfer Distance of Locomotive
In this paper a new reinforcement learning system for generating marshaling plan of freight cars in a train is designed. In the proposed method, the total transfer distance of a locomotive is minimized to obtain the desired layout of freight cars for an outbound train. The order of movements of freight cars, the position for each removed car, the layout of cars in a train and the number of cars...
متن کاملConcurrent Locomotive Assignment and Freight Train Scheduling
The locomotive assignment and the freight train scheduling are important problems in railway transportation. Freight cars are coupled to form a freight rake. The freight rake becomes a train when a locomotive is coupled to it. The locomotive assignment problem assigns locomotives to a set of freight rakes in a way that, with minimum locomotive deadheading time, rake coupling delay and locomotiv...
متن کاملNumerical and Experimental Analysis of Nonlinear Parabolic Springs Employed in Suspension System of freight cars
Nonlinear vibration of parabolic springs employed in suspension system of a freight car has been studied in this paper. First, dynamical behavior of the springs is investigated by using finite element method and the obtained results are then used in vibration analysis of a railway freight car. For this purpose, dynamics of a parabolic spring subjected to a cyclic excitation has been studied ...
متن کاملOptimisation of simultaneous train formation and car sorting at marshalling yards∗
Efficient and correct freight train marshalling is vital for high quality carload freight transportations. During marshalling, it is desirable that cars are sorted according to their individual drop-off locations in the outbound freight trains. Furthermore, practical limitations such as non-uniform and limited track lengths and the arrival and departure times of trains need to be considered. Th...
متن کاملA decomposition based hybrid heuristic algorithm for the joint passenger and freight train scheduling problem
We study the joint problem of scheduling passenger and freight trains for complex railway networks, where the objective is to minimize the tardiness of passenger trains at station stops and the delay of freight trains. We model the problem as a mixed integer program and propose a twostep decomposition heuristic to solve the problem. The heuristic first vertically decomposes the train schedules ...
