The failure rate is used, in order to determine the probability, with which a system precipitates, after it already functioned a time tkorrekt.

If f (t) is the Wahrscheinlichkeitsdichte for a loss, then the function determines

r (t) = \ frac {f (t)}{1-F (t)}

the real variable t the failure rate.

Alternatively one can represent the failure rate as

r (t) = - \ frac {D} {dt} \ LN (1-F (t))

and with it

F (t) = 1 - e^ {- \ int \ limits_ {0} ^ {t} r (x) dx}
