Mathematical modelling of the railway station’s technological parameters in transport corridor system of export traffic increasing volumes

Abstract

The study substantiates the need to develop mathematical analysis methods of railway station technology in the context of increasing the volume of freight traffic through the constituent elements of the infrastructure of the international transport corridor. The aim of the work is to develop proposals for improving the station operation technology under the conditions of its additional functions, to analyse the unevenness of the station transportation process and to assess changes in the transport corridor parameters. The object of the study is the Astrakhan-II station of the Volga Railway (JSC "Russian Railways"), located within the boundaries of the international corridor "North-South". In the article on the example of a particular station, its technical and operational characteristics, time norms for the performance of various technological operations, the unevenness of the station process is assessed, and a mathematical model of the station operation as a mass service system is developed. The "bottlenecks" are identified and proposals are formed to increase the processing capacity of the station, aimed at reducing channel utilisation and downtime duration. The results of the mathematical model are supplemented with technological proposals to change the formation plan of the Astrakhan II station to assist the port of Olya in picking up ship consignments in order to maximise the efficient use of Astrakhan II station capacity and reduce the need for track development in the port of Olya for marshalling operations, and consequently reduce the cost of its development. As part of compliance with the coordinated development of all elements of transport infrastructure, the capacity of the railway approaches to the station is assessed and a final set of measures is established.
