The purpose of the study is dedicated to improving the quality of sorting process using the developed method to determine rational regimes of the train breaking up. These modes provide maximum of reliability division of the wagon cuts at switches, as well as the possibility of implementing a safe speed collision of wagons in marshalling tracks. Methodology. Investigations of the separations of the cut of the train at switches were carried out using simulation modeling. For research, we used the model for the running cut from sorting hump, which allows us to realize the set exit speeds from the brake positions when adjusting the braking zone of the cut. Findings. A quantitative assessment of the indicators of the sorting process was carried out using the developed method for optimizing the braking modes of the cuts to control the process of decomposition of trains on one of the sorting hump of Ukraine. The performed analysis of the results showed sufficient efficiency of the developed method, which can be recommended for calculating the exit speeds of cuts from brake positions in automation systems of the sorting process. The braking modes obtained as a result of optimization can provide a sufficiently high quality of interval regulation, as well as the possibility of realizing a safe approach speed of cuts to vagons on the sorting paths of automated humps. The scientific novelty of the work is to prove the effectiveness of the considered method of optimizing the composition breaking mode. Practical value of the thesis as well as developed models and methods can be used to create an automated process control system for breaking up of the stocks on sorting humps, as well as to assess the quality of the construction of projected sorting humps. Automation of humps will help to improve the economic performance of stations, reduce the cost of processing cars, save energy for braking cuts and shunting, improve working conditions and safety of workers of the sorting hump.
