IEEE Transactions on Reliability, 1978
This paper considers a reliability model in which the failure rate increases linearly in time. Methods of parameter estimation are discussed, and two applications are given.

Relationship Between System Failure Rate and Component Failure Rates
Technometrics, 1963A simple sufficient condition is given for a system to have an increasing failure rate when the identical components comprising it have an increasing failure rate. Systems which function if and only if at least k of the n components function (“k out of n” systems) satisfy this condition.

Failure rate — a unified approach
Journal of Applied Probability, 1976Aging, of biological and mechanical systems, is well described as ‘deterioration of the power to withstand destruction.’ The failure-rate concept is the mathematical way of describing aging. Failure rates have been defined for discrete and continuous time and used extensively, particularly in actuarial science and reliability.

In our everyday life, we are frequently much more interested in the reliability of used goods than new ones. When someone buys a clock, the consumer has a warranty from the store ensuring that he can replace the clock with a new one or have it repaired if the clock fails within a certain period of time.

Current Opinion in Cardiology, 2016
Resting heart rate has long been thought to be a risk factor in cardiovascular disease and a prognostic factor in heart failure. β-Blockers were originally used in heart failure for their heart rate control abilities. However, they also have negative inotropic effects contributing to their overall benefit.

Tests for the equality of failure rates
Biometrika, 1985Summary: A new statistic is proposed for testing the hypothesis \(H_ 0\) that two failure rates are equal against the alternative hypothesis \(H_ a\) that one failure rate dominates the other. Unbiasedness, asymptotic normality and consistency of the test against \(H_ a\) are shown.

Some considerations concerning the concept of failure rate are presented. For a semi-Markov process are given equations of Markov renewal type using the failure rates of passing from a state into another. The existence and uniqueness of the solutions is discussed.

Probability in the Engineering and Informational Sciences, 1999
Consider a family of distributions with survival distributions that are log concave and stochastically increasing in a parameter over which it will be mixed. It is shown that a necessary and sufficient condition for a mixture over any such family to have an increasing failure rate is that the mixing distribution have an increasing failure rate ...
