A number of problems in the reliability theory as applied to technical systems is considered
for the case when the time-to-failure values are distributed as a mixture of two exponential distributions.
This consists of finding a renewal function for a simple restorative (renewal) process, a comparison
of three operating strategies according to the criterion of minimal cost intensity and using the
method of moments to find point estimates for the parameters involved in the mixture. The choice of
the mixture is caused by the fact that its failure rate has a running-in period that is characteristic within
the initial operation period of technical systems, whereas afterwards, the failure rate is almost constant.
This distinguishes the considered mixture from the exponential distribution with a constant failure
rate widely used in the reliability theory.
