Abstract
The mechanism of application of simulation modeling methods for the analysis and optimization of technological processes at marshalling yards in the context of digitalization of railway transport is described. The main focus is on the first phase of car processing, which involves the arrival and breaking-up of trains. Using the AnyLogic software package, a simulation model has been developed that reproduces the logic of interaction between railway transport units. The model provides visualization of the technological cycle, assessment of the impact of changes in parameters such as processing time, crew size, and arrival intervals on the station's capacity, and identification of bottlenecks in the technological chain. Analytical conditions for synchronizing the arrival, processing, and disbanding flows have been established and formalized as inequalities. The modeling process is completed either after a specified time or when the critical level of the reception yard occupancy is reached, which allows to estimate the limit capacity of the station under given technological and infrastructure constraints. The results obtained can be used at the stages of design, modernization and operational management of marshalling yards.
