Query: Reconstruction Models for Attractors in the Technical and Economic
  Processes   The article discusses building models based on the reconstructed attractors
of the time series. Discusses the use of the properties of dynamical chaos,
namely to identify the strange attractors structure models. Here is used the
group properties of differential equations, which consist in the symmetry of
particular solutions. Examples of modeling engineering systems are given.
