“…In a real situation, it is not always possible to measure the selected physical parameters in existing units of measurement, and then they resort to replacing them with indirect ones, informationally correlated with physical parameters, which are called diagnostic S. In Figure 1, the set {Si} is a set of diagnostic parameters, and f(s) is a function of the distribution density of some conditional diagnostic parameter. As follows from Figure 1, the process of managing the organizational and technical system consists of the following sequence: In most of the known works, this is the end of the control process [10]. At the same time, the main attention was focused on the quantitative assessment of control errors (control risks), which were functions of the statistical properties and characteristics of the above agents of the control system [11]- [16].…”
