In-process for a decision task of prognostication of casual sequence of change of the state of the technical system information technology of determination of optimum values of interval of aftereffect and order of nonlinear connection of the probed casual sequence is proposed. The algorithm of extrapolation and technology calculate its optimum performance are based on nonlinear canonical decomposition.
There grounded the frequency range choice in the system of the operation reliability of the technical systems based on the application of probabilistic – statistical method.
The results of theoretical research on reliability indices of combine harvesters subsystems for effective realization of harvesting in short periods of reaping have been considered.
