The questions of mathematical modeling and numerical analysis (NA) of the unstationary non-isothermal (UN) modes of operations (MO) of the gas-transport system (GTS) are examined. The classes of tasks of mathematical modeling and NA UN MO of the GTS are formulated. The solution of which comes to the solution of the interconnected systems of differential equalizations (DE) in partial derivative of hyperbolical type, were given on a graph of GTS with the prescribed initial and boundary conditions (BC). The class of tasks, which differs from the known fact that in this class of tasks the BS set not only in external graph junction but also in the intermediate. The method of solution of the formulated classes of tasks is offered.References
