Formation and Optimization of Transport Networks in the Conditions of the Digital Integral Environment for Transportation

Abstract

The article provides a brief description of the digital integrated transportation support environment. The methods of choosing the base route in the formation of transport networks in the conditions of the formation of a digital integrated environment are presented. It is shown that the means of solving the problem of optimization of transport networks is a developed modeling complex, which consists of a set of models with the necessary degree of detail. The paper presents a functional diagram and a brief description of the complex. The complex functions taking into account the replenishment, improvement and updating of models, allow you to combine different types of models and use the necessary of them when solving specific problems of transport network optimization. The modeling complex allows to significantly simplify the optimization of transportation networks. On the basis of the proposed mathematical apparatus, the software of an automated system has been developed, which is designed to function in a digital integrated environment, a brief theoretical description of which is given.

Infrastructural constraints impeding the development of high-speed freight rail transportation in Russia

“…In the interview with the Deputy General Director of JSC "Russian Railways", published in the "Gudok" newspaper on December 27, 2021, Alexey Shilo said that in order to organize transportation of containers as part of container trains in 2021, according to the requests of the organizers of container trains and subsidiaries, there were about 1 thousand specialized schedules (including 220 for international container trains). A similar number of timetables have been planned for 2022, and their number will be increased as requests from container train organizers are received [7]. This indicates the expanding scope of the container fleet use in the near future.…”
