Algorithm of cars' presence on non-public tracks as a basis for improving the quality of operation of the «railway - clients» system

Non-public railway tracks and junction stations of mainline railway transport are the most important links of the «railway - clients» system. At these points, car traffic is generated and extinguished, as well as information and documents are exchanged. When organizing interaction, it is necessary to take into account the interests of not only the carrier and the owner (user) of the non-public track, but also the owners of rolling stock. The most effective solution is to develop an automated interaction management system. The purpose of the work is to determine the factors that lead to idle of cars while waiting for technological operations to be performed with them. This will allow you to find control solutions aimed at eliminating (reducing) the negative impact on the operation of the “railway - clients” system. To achieve this, an algorithm has been developed for the presence of a car on non-public railway tracks, and factors that have a negative impact on the idle of cars on non-public tracks have been identified. The proposed algorithm is the basis for developing a mathematical model for calculating the time spent by a car on non-public tracks. The presence of cars on non-public tracks is presented as a control object for the subsequent development of an automated control system for the interaction of junction stations and non-public tracks. It will have a comprehensive approach to calculating the costs and risks of all participants in the «railway - clients» system.
