Abstract EN
An operational process at train marshaling yard is considered in this study.
The inbound trains are decoupled and disassembled into individual railcars, which are then moved to a series of classification tracks, forming outbound trains after being assembled and coupled.
We focus on the allocation plan of the classification tracks.
Given are the disassembling and assembling sequence, the railcars connection plan, and a number of classification tracks.
Output is the assignment of the railcars to the classification tracks.
An integer programming model is proposed, aimed at reducing the number of coupling operations, as well as the number of dirty tracks which is related to the rehumping operation, and the order of the railcars on the outbound train must satisfy the block sequence.
Tabu algorithm is designed to solve the problem, and the model is also tested by CPLEX in comparison.
A numerical experiment based on a real-world case is analyzed, and the result can be reached within a reasonable amount of time.
We also discussed a number of factors that may affect the track assignment and gave suggestions for the real-world case.
