The maintenance of a single unit system that alternates operating and idle periods is studied. In the former case the failures are detected as soon as they occur and only by special testing or inspection in the latter. This paper aims at minimizing the cost per unit of time for an infinite time span by selection of a unique interval, for both inspection and(More)
It is quite plausible that any device or system reliability shows an increasing failure rate (IFR) as age, use or both may cause it to wear out over time. Nevertheless, explaining a decreasing failure rate, which means an improvement as time goes by, is far from intuitive. Mixtures of lifetime distributions turn out to be the most widespread explanation for(More)
