The difficulty of assessing the state lies in a little predictable change in the dimension of a dynamic system under the influence of internal changes and environmental parameters. In the work, the state of such a system is estimated by the method of integral indicators. The application of the method of integral indicators allowed us to evaluate the activity of an enterprise. In the present work, the method of integrated indicators is used to assess the control of a digital copy (enterprise). Using the author’s complex of programs, the activity of an enterprise (digital copy) is modeled as a dynamic non-stationary, in structure, system of 1.2 million values with spaces identified at each time step: output data, control data, and environmental parameters. The research showed significant changes in the values of the integral indicator characterizing the state of a dynamic system when implementing different regimes of control for a woodworking enterprise and a construction company. In the first and second examples, an underestimation of the invisible material flows of production processes of “shadow” businesses-processes were found to be 4.5 billion rubles per year. In the third example, the loss of the enterprise from stop businesses-processes for 4 years will amount to 188.8 million rubles.
