Titov M. The rise if the efficiency of technical frontier transmission stations functioning of Ukrainian railways.

The work to be defended includes researches devoted to the questions of the rise of the efficiency of technical frontier transmission stations functioning of the Ukrainian railways, rationalization of their work and technical equipment. The analysis made and formalization of production processes have chown mutual dependence in carrying-out the main operation. The worked-out schedules of conditions of two-, three- and four- phased SMS are describing the functioning of the active cycles of the technological lines in the sub-system of receiving and dispatch of the frontier transmission station. The mathematical model of defermining the rational technical and technological parameters of fronties transmission stations has been realized in the form of the accounting programmes of parameters which characterize the power of the "receiving" and "dispatch" sub-systems. Sorting the variants of technical and technological equipment or the devices which provide the service of the flow with the help of PC the minimization of C parameter - the whole economic expenditures is being held. The account have show that the variant of the organization of the work of frontier transmission stations under the conditions of the maximum simultaniety of operations has it's benefit from the economic point of viem though it requires additional capital investments. Key words: frontier transmissions, technical and technological parameters, sub-system, mathematical model, economic expenditures.
