Process organisation modelling for maintaining rail track geometry

Introduction. The increase in freight traffic density and axial loads on the Eastern polygon is affecting the condition of the railway and reducing the time available for maintenance. The increased workload caused by track deformation in difficult operating conditions makes the planning and organisation of railway maintenance work much more difficult. One of the main factors affecting the safety and smooth running of trains is the geometry of the rail track, which is kept in a normal condition by track maintenance. The study examines the problem of increasing the efficiency of maintaining rail track geometry.

Materials and methods. Mathematical modelling and statistical methods were used to solve the problem. A process organisation model was created based on formalising the process of incoming and outgoing work. The estimated workload required to rectify the identified deviations was determined on the basis of the results of the track condition assessment using track measuring devices, taking into account the regulatory time standards for their rectification.

Results. The mathematical model for the process organisation of rail track geometry maintenance is presented, which allows to determine the necessary level of daily workload on a linear section to perform the full scope of works within the regulated terms, which would reduce the desicion time during the planning of works.

Discussion and conclusion. The use of this model makes it possible to simplify the planning and organisation of work on a section of track, which is particularly important at a high level of urgent and high-priority work on particularly heavy-traffic sections. Further research would focus on the development of a mathematical model, the development of a software product and its implementation into a unified enterprise automated infrastructure management system.
