“…The use of a multi-section technological mechanism, proposed in [1,2], makes it possible to take as a basis the assessment of the operation of systems with a portioned supply of a technological product and improve the proposed approach. Thus, a continuous technological process undergoes short-portion processing with the number of sections depending on the specificity of the process.…”

“…However, with the advent of the possibility of increasing the number of degrees of freedom of control over technological mechanisms, it became possible for technological processes to work with a parallel change in control trajectories under the dynamically changing external environmental conditions [1,2]. That made it possible to make adjustments to the production process in real time [3].…”

“…Studies of the levels of blood oxygenation (saturation), that is, the percentage of oxygen saturation of hemoglobin, became increasingly active as a result of the coronavirus pandemic (COVID-19). The first stage of this viral disease is characterized by «latent hypoxia» due to insufficient oxyge nation of the patient's blood [1][2][3]. Hypoxia, or lack of oxygen, can be almost unnoticeable for saturation levels close to 90 % and below.…”

This study relates to the field of verification of cybernetic estimates of the use of reserves as criteria for the effectiveness of transformative class systems with a continuous supply of a technological product. The task set here attracted even more attention after the advent of improved approaches that make it possible to automatically change the control trajectories of technological systems in real time. In such cases, the assessment of the current status of the process and the efficiency of stock management has become an integral part of the operation of the management subsystems. Therefore, the development and verification of cybernetic assessment of effectiveness for such control systems is a relevant issue. The first stage of the reported research involved the development of a cybernetic model of operation with distributed parameters. Four formal features have been proposed. Finding integral functions of these features has made it possible to obtain an idea of some quantitative characteristics of the process while finding the second time-dependent integral characteristic has made it possible to represent the physical and cybernetic parameters of the process. At the second stage, formulas for calculating the main assessment indicators were proposed; their verification was carried out under three different control trajectories, which showed the adequacy of the devised approach. The final step was to develop three variations of the efficiency formula, which is calculated at set points in time throughout the entire production cycle. Thus, cybernetic assessment of the effectiveness of the use of reserves makes it possible to formalize and fully automate the processes of optimization and adaptation of the functional systems of an enterprise
