Popis: Background. When choosing a mathematical model of reliability of non-recoverable items, it is necessary to know in advance the conditions under which the mean operating life is finite and when it is infinite. Therefore, the actual problem is to find signs of convergence and divergence of operating life integrals. Materials and methods. In this paper, estimating the mean operating life through a function of the failure rate of non-recoverable items, sufficient conditions for convergence and divergence of operating life integrals are found. Results. On the basis of the found signs of convergence and divergence of integrals of the operating life of non-recoverable items, the conditions of limitation and unlimited values of the mean operating life are determined. Conclusions. Sufficient conditions for convergence and divergence of integrals of the operating life of non-recoverable items are proved. Examples of the use of the obtained results are given.
