IMPROVEMENT OF TECHNOLOGY FOR CARRIAGE OF SINGLE WAGON LOAD AND GROUP SHIPMENTS ON THE BASIS OF RESERVATION OF POSITIONS IN FREIGHT TRAINS

. This article explores the problem of increasing the efficiency of freight transportation by single wagon load and group shipments on Ukrainian railways. It is proposed to improve the process of scheduling transportation based on booking seats in freight trains. Quantitative and qualitative indicators of the operational performance of the railway systems of Ukraine (Ukrainian railway) and Switzerland (SBB-CFF-FFS) have been studied, with the aim of formulating effective proposals for improving the efficiency of operating work with rail and group shipments of Ukrainian railway holding. The model of the phase movement of freight trains for carriage of freight carriages in the SBB-CFF-FFS network is investigated. The functions of the "CIS-Online" system for booking of seats in a freight train for the planning of transportation by wagon and group shipments are analyzed. In order to increase the efficiency of the technology of carriage of single wagon load and group shipments on the railway network of Ukraine, it is proposed to formalize the technology of carriage of wagon shipments between stations with the possibility of booking seats in trains. An advanced mathematical model that minimizes the cost of train traffic and shunting work on the railway network, capacity of stations, the processing capacity of stations and the maximum number of wagons in the train. Experimental researches have been carried out and a rational variant of the plan of formation of single wagon load and group shipments has been found, and the timetable and routes of the train carriage on an arbitrary graph are attached to the threads. The application of the proposed approach will allow for the transparency and accessibility of freight carriage services and, as a consequence, will adapt the technology to the growing demands of logistics.
