ABSTRACT

The paper shows that treating failure-free time in the three-parameter Weibull distribution not a constant, but as a random variable makes the resulting distribution much more flexible at the expense of only one additional parameter.

KEYWORDS

Weibull lifetime model, randomised failure-free time, compound Weibull distributions
