Component Reliability Tutorial

Reliability of a component is finding out the probability that the component will perform under
it’s normal operating conditions for a set period of time. Reliability therefore, can be shown as
a probability distribution as shown in Figure 1.

graph shows a number of failures at low t (Infant Mortality). Towards the end of life
there is a large increas……
