Abstract

The efficiency of using locomotive and carriage fleets on the railway network is largely determined by the quality of train formation planning at marshalling stations. Automation of planning involves the use of mathematical models. The article describes the optimization flow model of the main technological line of a marshalling station. An important feature of this model is that it was able to adequately reflect not only the process of moving car flow at each stage of processing (when preparing trains for disbandment, during their disbandment, while accumulating cars in the marshalling yard, at the end of the formation of trains and rearranging them into the fleet departure, when preparing trains for departure and when leaving the station) also including an important part of the train formation process which is the provision of formed trains with locomotive crews. It is assumed that the model will be used in an automated control system and will improve the natural and economic performance of a complex transport system - a marshalling station.
