Improvement of the planning method of the sortation system

Objective: Determination of the minimum time spent by a transit car with processing at the marshalling yard, identification of the optimal car flow in order to optimize the loading of the station’s technical devices. Methods: The description of interoperational downtime is carried out by the theory of queuing, simulation modeling is used to recreate technological processes at the marshalling yard. Results: As a result of the analysis of the average time spent by the car at the station, a model of the marshalling yard was built, taking into account the monthly irregularity of the flow of the processed flow. Practical importance: With the help of the obtained data, it is possible to improve the long-term planning of the work of the sortation system, to determine the optimal load of the station’s technical means. By changing the station’s constant parameters (the number of tracks) and variables (the number of maintenance crews, the number of shunting locomotives), it is possible to respond flexibly to the required development of the car traffic made by the station.
