Estimation of operation reliability of control electronic systems with the use of maximum product problem

In the article there are presented the results of analytical research on the operation reliability of a complex engineering system using the example of a control electronic system. Functioning of such a system is suggested to be considered with the use of a maximum product problem. At the same time an adequate balance between its reliability and efficiency is chosen as a criterion for the estimation of its reliable and efficient functioning. We consider the electronic system in the conditions of modern industry to be one of the most loaded subsystems. The analytical expressions have been obtained which allow setting the optimal balance between the reliability and efficiency of control electronic system operation.

The offered approach allows more effective and adequate estimation and prognosis of the state and performance of any electronic system at all stages of its life cycle, from the beginning of exploitation to the end of the warranty period, and, in many cases, during the extension of this period, on the basis of the continuous control of the balance in accordance with the maximum product problem.
