Abstract

Modern technical systems contain, as a rule, a large amount of elements that may fail in the process of its operation.
To ensure high efficiency of the use of a technical system throughout the assigned lifetime, it is necessary to carry out its maintenance in order to identify possible failures and restore the up state of the system.
Discusses the issues of determining the duration of the interval between checks of the serviceable state of a technical system with duplication of channels and monitoring the health of each channel according to the criterion of a set value of availability function.
The possibility of approximate estimation, as well as the effect of the degree of approximation of the objective function on the efficiency of the use of the technical system, is investigated.
Studies have been carried out to determine the interval between checks of the technical system serviceability with duplication from the condition of meeting the requirements for its effectiveness.
It is shown that this approach can significantly reduce the number of checks compared with the optimal strategy and provide an economic effect.
