MODELING OF THE RAIL FREIGHT TRAFFIC BY THE METHOD OF ECONOMIC-GEOGRAPHICAL DELIMITATION IN THE REGION  OF THE SOUTH-EASTER COAST OF THE BALTIC SEA

The results of further research on the creation of a mathematical model of railway freight traffic carried out in a regional transport and technological system are presented. The proposed logistic approach is applied to the issues of optimizing the management of transportation directed to ports located on the southeast coast of the Baltic Sea. Built on the basis of a comprehensive assessment of the transport infrastructure of the region under consideration and the performance of the operating

ECONOMIC–GEOGRAPHICAL METHOD DELIMITING WAGON FLOWS IN THE REGION CONSIDERED: MODEL AND ALGORITHM

freight traffic. The algorithm for creating a model of freight transportation is based on the analysis of the qualitative and quantitative indicators of the operator company in the considered region with the use of analytical, heuristic, and graphic capabilities of math software. The theoretical substantiation of the territorial picture, the freight transportation market in the region is obtained. The carried-out research allows to specify possible ways of optimization of freight traffic distribution.

METHODS OF SUBSTANTIATION OF SPECIALIZATION OF RAILWAY LINES

The article proposes methodological principles for substantiating the specialization of main railway lines based on the primary types of passenger or freight traffic in order to improve the level of transport services, economic efficiency, and reliability of the transportation process. The search for a solution to the problem provides a rational distribution of transport flows and investment measures, with the subsequent finding of a compromised operation for a set of effective alternatives.

A MODEL OF TRANSIT FREIGHT DISTRIBUTION ON A RAILWAY  NETWORK

The peculiarity of the transit freight transportation by rail in international traffic is the fact that while performing transportation, the railway administrations are in competition among themselves. At the same time, the routes of cargo traffic volumes significantly depend on the conditions of transportation by railways of individual states. The mathematical model for the distribution of transit freight traffic volumes on the railway network, based on the methods of graph theory and game

THE INFLUENCE OF THE «TRAIN-TRACK» SYSTEM PARAMETERS ON THE MAXIMUM LONGITUDINAL FORCES' LEVEL

difference of gradients and the length of the horizontal area that separates two gradients with opposite signs are estimated. The proposed mathematical model and methodology can be applied during standardization of the longitudinal profile's parameters from the point of view of the freight traffic safety for the trains of various length.
