Logvinova N. Increase of efficiency of organization of motion of trains on railway directions with parallel motions it is Munuscript

Dissertation is devoted the questions of increase of efficiency of organization of motion of freight trains on railway directions with the purpose of determination of rational sizes of motion of trains on parallel motions in the conditions of speed motion of passenger trains and wholesale of electric power. In dissertation first formulatrd and decided optimization task in relation to organization of train on railway directions with parallel motions in the conditions of the differentiated tariffs on electric power, that allows to cut down e[penses railway on advancement of freight trains.The estimation of dependence of charges is improved on advancement of freight trains at distributing of motion between to parallel motions in the period of daily motion of speed-up passenger trains of the basis of decision of a task the methods of the nonlinear programming. Improved economy-mathematical model of railway directions with parallel motions, the use of which allows to define the most rational distributing of train on the areas of dirrections. The method of calculation of carrying capacity of railway areas, which unlike existing allows to take into account the presence of speed motion of passenger trains in daily daypart, is smproved.
