The Basics of Burn-in,s (infant mortality) of components before they are shipped to customers or put into field operation. Usually, to burn-in a component or a system means to subject it to a fixed time period of simulated use prior to the actual operation. That is, before delivery to the customers, the components are ex

Burn-in for Repairable Systems,, obviously, it is just scraped and discarded. However, an expensive, complex product or device will not be discarded on account of failure of its part, but rather a repair will be performed. Therefore, in this chapter, we deal mostly with repairable items. Note that the contents of this chapter are

Burn-in for Heterogeneous Populations,tub-shaped (BT), burn-in can be usually justified. Note that, as mentioned and illustrated earlier, the heterogeneity of populations is often a reason for the decrease in the resulting failure rate, at least, in some time intervals. In this chapter, the optimal burn-in procedures are investigated wi

Shocks as Burn-in,ten the length of this procedure, burn-in is most often performed in an accelerated environment. This indicates that high environmental stress can be more effective in eliminating weak items from a population. In this case, obviously, the larger values of stress should correspond to the shorter dura

Stochastic Models for Environmental Stress Screening,hich is a method of ‘elimination’ of initial failures (infant mortality). As was mentioned previously, the ‘sufficient condition’ for employing the . burn-in is the initially decreasing failure rate. For example, when a population of items is heterogeneous, and therefore consists of subpopulations w

Burn-in for Heterogeneous Populations,trong items due to, for example, defective resources and components, human errors, unstable production environment, etc. In the later part of this section, we will also consider the continuous mixtures model.

Introduction,ewal process). By a ‘shock’ we understand an ‘instantaneous’, potentially harmful event. Depending on its magnitude, a shock can destroy an operating system (failure), leave it unchanged (as good as old), or, e.g., increase its wear (deterioration) on some increment. Numerous shock models were devel
