Assessment of the Effectiveness of Monitoring the Technical Condition of a Complex Technical Object, Taking Into Account Expert Assessments

   The purpose of the research is to develop a method for evaluating the effectiveness of monitoring the technical condition of a complex technical object, taking into account expert assessments.

   Methods. Evaluation of the effectiveness of the application of a complex technical object is carried out with the help of appropriate performance indicators that characterize the degree of fulfillment of the tasks assigned to them. When choosing performance indicators, the following basic requirements should be taken into account: the indicator should have a quantitative expression and be calculated simply enough; the indicator should be selected taking into account the specifics of the task being solved and reflect the main characteristics of the phenomenon being evaluated; the
indicator should be representative and ensure comparability of the evaluation results by the degree of preference, i. e. to prevent incomparable (indifferent) decisions.

   Results. A method for evaluating the effectiveness of monitoring the technical condition of a complex technical object is presented, taking into account an additional expanded information description with qualitative features (expert assessments).

   Conclusion. The effectiveness of the control directly depends on the accuracy and completeness of the control. The accuracy of existing control systems is quite high, but the completeness of control does not always take into account qualitative (expert) assessments about the object of control. Improving the efficiency of control systems should go not only at the expense of accuracy and speed, but also at the expense of completeness of control. As a criterion for evaluating the effectiveness of the control system, an assessment of the probability of a functional state of a controlled complex technical object is proposed. The calculation of the effectiveness of the control system is proposed, taking into account the additional expanded information description by qualitative signs (expert assessments) about the object of control. It is shown that it is possible to more accurately assess the operational state of the object of control if the completeness of control is higher, with an irreducible accuracy of control.
