Abstract
Purpose. 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. Originality. The scientific novelty of the work is to prove the effectiveness of the considered method of optimizing the composition breaking mode. Practical value. Scientific results 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.

SEPARATION OF COMPOSITION ON THE SORTING HUMPSThe 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
Automation of the process of disbanding trains is one of the main ways to improve the efficiency of the operation of sorting humps, improving the quality of the process of disbanding the compositions and effective using of technical facilities.Creating a modern automated control system for the sorting process would improve the productivity of sorting humps, reduce downtime of wagons at sorting stations, and due to this way speed up the process delivery of goods, reduce the turnover of wagons and their fleet
It is necessary to search for such BM, at which the calculated intervals on the separating elements between all detachments of the composition reach a maximum. This will preserve the minimum interval between cuts, necessary for their successful separation in the event of an adverse combination of influencing factors occurring and thereby reducing the likelihood of nonseparation during the dissolution of the compositions on the sorting humps
