Procedure and algorithmization of calculation of terminal network parameters

Abstract

It is impossible to implement trans-regional integration without a regional logistics system based on a network of storage and distribution centers. The search for the most suitable project of a terminal network is complicated by the necessity to perform a step-by-step processing of options. Decisions are made considering the economic performance of the cargo transportation process. The target function has been formulated in the article. A sequential decision-making process based on the number and dislocation of terminals has been developed with a calculation model, and an algorithm for designing a regional terminal network is proposed. A terminal network is considered as a systemically important basis to implement the integration of all transport-expediting processes in the region. The advisability of formation of the regional terminal network to support the logistics of cargo transportation has been substantiated. The paper proposes a methodology for stepwise solution of the task to determine the required number and parameters for location of the logistics storage and distribution centers (LSDCs). The basis of a calculation process is an estimation model. The application of the proposed methodology will enable improving the existing terminal network of the Russian railway transport, enhancing the efficiency of cargo transportation, and facilitating the increase in competitiveness of RZD OJSC in the cargo transportation market.

“Smart station”-a complex of automated control system

“…Local elements of the transition to digital technology (queue congestion control, ticketprinting machine (BPA), screening frames and X-ray television installation, Face ID system As for the tasks of passenger infrastructure operation, this digital platform "Smart Station" will ensure proactive work based on forecasting, calculation, and risk assessment, as digitization and process monitoring will exclude the human factor, especially if it is relevant to transport safety issues [18][19][20][21]. Even now, due to the implementation of digital technologies and local projects, the support of cross-selling activities for suburban and longdistance trains is noticeably increasing.…”

Methods for calculating and analyzing the capacity of a railway line with mixed traffic

“…Table 1 below shows the movement of trains between these stations [17]. Calculations can be made with complication of the modeling cycle and inclusion of calculations by the methods outlined, for example, in papers [18][19][20].Taking into account the time of departure and arrival of trains and intermediate stops, we find the value of the average route speed of the train on each of the sections of the polygon by the following formula 3.…”

Calculation of service devices in the projected traffic-transfer hub

“…Thus, the savings of reduced costs amounted to 6114.7 thousand rubles/year. It should be noted that when carrying out technical and economic calculations, it is possible, in addition to simulation modeling, to use the tools and methods of the theory of terminality, logistics, situational, and process management [26][27][28][29][30].…”
