Coordination of Parameters of Transport Elements System in the Conditions of Lack of Traffic and Estimated Capacity

The paper deals with the balanced development problem of the infrastructure of railway transport enterprises, aimed at improving the economic efficiency of their operation. In order to solve the problem, it is proposed to use an approach, according to which the interaction of its elements is taken into account for calculating the capacity of the transport system. In other words, the traffic and estimated capacities of the station devices (“channels”) is determined considering the reserve capacity of the preceding elements (“bins”). Bins carry out an important task, they reduce flow irregularity, thereby increasing the load factor of subsequent servicing devices. Inefficient interaction of elements means economic losses in terms of excess or lack of capacity. Therefore, in order to achieve economic efficiency of railway enterprises, the elements in the structure have to interact efficiently, which implies the harmonization of the parameters of elements according to some criterion. In order to organize the effective interaction of elements at the “bin + channel” level, the balanced traffic capacity criterion was formulated. Speaking about the elements inside the “bin + channel” structures, the final decision on their coordination is made based on the minimum capital and operating costs criterion. As a result, based on the developed criteria, the methodology for coordinating the parameters of structural elements of railway stations is proposed in the paper. The methodology ensures minimization of capital and operating costs of the transport system as a whole.
