Objective: to develop a methodology for selecting dislocation stations for trains set aside from traffic, taking into account capacity, technical equipment, and minimal deviation from the freight train route to ensure uninterrupted functioning of railway infrastructure under conditions of high load on transport system elements. Methods: the theoretical basis of the study included analysis of operational work of railway stations and sections, and mathematical modeling of transport processes. To formalize the problem of selecting dislocation stations, graph theory was applied, allowing the representation of the operational area as a weighted directed graph. Minimum costs for determining dislocation stations are proposed to be calculated using Dijkstra’s algorithm. Results: a multi-criteria optimization problem for selecting a dislocation station was formulated and solved. A mathematical model for selecting a dislocation station is proposed, including a system of constraints on the technical equipment of the station and the reserve capacity of hauls. Practical importance: application of the proposed methodology will allow finding the shortest routes to dislocation stations for temporary setting aside of freight trains, considering given constraints. The developed solution will increase the efficiency of the transport network, reduce the carrier’s operating costs, and minimize risks of violating cargo delivery deadlines. Implementation of the proposed approach will create conditions for forming a controlled “buffer” of set-aside trains, preventing paralysis of stations and sections and ensuring sustainability of the transportation process under infrastructure limitations.
