Lazaryan popup.description2 The work is devoted to the issues of increasing the efficiency of the functioning of the sorting hills by improving the methods of simulation modeling of the sorting process. The object of the study is the process of disbanding and forming freight train trains on the sorting hills. The subject of the study are the interrelationships of the technical and technological parameters of sorting slides and the characteristics of railways with the operational performance of the railway stations. In the work, methods for estimating the dynamics of the roll-off of the hooks from the slide are improved by taking into account the random nature of their parameters and the conditions for their rolling. This allowed us to investigate the influence of the inhibition regimes on the parameters of the distribution of random values of the speed and time of the trajectory rolling. The problem is formulated of the choice of braking regimes for the traps of the composition, as a result of which the speeds of their exit from the braking positions are determined, which ensure the minimum window size on the sorting tracks and the minimum risk of non-separating the traps on the arrows for a given safety level of the sorting process. The simulation methods are used to estimate the effectiveness of the implementation of the estimated speed of approaching trailers to wagons on sorting tracks and to improve the accuracy of realization of retarded speeds by retarders.
