SIMULATION MODELING OF PARAMETERS OF FUNCTIONING OF RAILWAY PROJECTS

Abstract

The speed of communication on any route, directly and indirectly through the function of redistribution of traffic volumes, causes an increase in the number of movements, traffic volumes, transport work, in the network of the appropriate type, at the same time the values of the medium system coefficient of passenger capacity use and the number of vehicles may vary both in the direction of the increase and vice versa. The results of the calculations of the basic parameters of the functioning of intercity passenger route systems for various values of the speed of communication on intercity railway routes established the appropriate mathematical model for determining the parameters of this passenger communication. The conducted analysis of simulation methods has determined the possibility of using for the determination of quantitative parameters for changing the basic indicators of the operation of the system of intercity passenger route methods of mathematical and computer simulation. The results of the work determined the basic indicators of the functioning of the system of intercity passenger route transportation. These indicators include: the number of movements in the network; volume of transportation; transfer ratio; transport work; average distance of the route; average distance of the network ride; medium coefficient of passenger capacity use; required number of buses / cars. According to the analysis of the methods and models of calculations of the basic indicators of the functioning of the system of intercity passenger traffic, it was assumed that the change in the quantitative characteristics of the parameters entering into the system or the quantitative characteristics of its elements may lead to a change in the quantitative indicators of the functioning of the system itself or its individual elements.
