Mathematical modeling of technological operations performed by trains at stations

Abstract

The main purpose of the work is mathematical modeling of the sequence of technological operations performed by trains at stations. Methods of systematic analysis, analytical, regression and graphic modeling, flow mapping of the sequence of technological actions were used. The methods of normalizing the time of stay of trains at stations and their advantages, the degree of interconnections and disadvantages of technological actions were studied. At the station, the time spent on the technological actions performed with the train was analyzed and the factors that negatively affect their execution were determined. In order to increase the level of execution of station performance indicators, it was recommended that the method of basic normalization of the time for performing technological actions with shunting and train locomotives depends on the length of the half-trip, the number of connecting and disconnecting wagons and the speed of the shunting. This method allows you to analyze the indicators of the time spent on technological actions at stations and the graph of train traffic (GTT), as well as increase the carrying capacity of rail transport by 7-11%.
