Abstract

Problem Statement (Relevance). The trend towards digitalization of management activities to improve their quality and efficiency creates prerequisites for solving the problem of real-time management of railway transportation. Increasing requirements of structural subdivisions of mining enterprises to the timeliness of transportation and the desire to reduce transportation and storage costs as a result of reducing the size of the transportation lot lead to the complication of both the composition of trains and the technology of their processing at industrial railway stations. The task of optimizing the processing of trains and the movement of car uncouples on the public tracks of large mining enterprises with a complex scheme of track development becomes critically important. Objectives. The design of the method of digitalization of railway transportation is based on the automation of formation and selection of the optimal sequence of shunting operations both at a separate industrial railway station and on the railroad transportation of industrial enterprises. Methods Applied. It is shown that the realization of the developed method is possible by describing the scheme of track development of a railway station by a two-vertex graph. Originality is a new mathematical object - a two-vertex graph with separate bijective vertices and edges, which provides a correct representation of the railway station track scheme in the simulation model as a result of additional consideration of the angle between the graph edges. Result. The possibility and efficiency of digitalization of railway transportation as a result of automated construction of optimal shunting routes using the algorithm of two-vertex graph optimization is proved. This feature of the proposed graph allows to correctly describe railroad switches in the simulation model. In addition, using the proposed graph to provide an effective search for optimal (shortest) paths using known methods without the need to perform additional calculations for the correct modeling of train routes along the tracks of the railway station. Practical Relevance. The developed method allows working out optimal decisions on management of shunting work at railway stations and is offered for implementation as a part of simulation models and intelligent transportation systems.
