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.

AbstractA regional bridge failure database was used to determine the bridge failure rate with associated causes. Using a sample population from one DOT over a 25-year period, the average number of bridge failures was approximately 1/4,700 annually with a 95% confidence interval from 1/6,900 to 1/2,700 annually.

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.

Abstract In this article bivariate failure rate is defined, and it is shown that no absolutely continuous bivariate distribution with constant failure rate exists except in the special case when the marginals are independently distributed.

Failure rate is the most commonly used term in reliability and related engineering interests, yet it is still not well understood by perhaps the majority of those using it. Indeed, more than one reliability treatise wrongly defines failure rate as a conditional probability density, i.e., wrong by the accepted criterion of what constitutes any ...

Failure mechanism based failure rate model
2009 9th International Conference on Electronic Measurement & Instruments, 2009For electronic products, the typical failure rate curve takes on three-stage bathtub shape, while few failure rate equations can describe the bathtub shaped curve. Based on environment load impact failure mechanism, the present paper develops load-property interference failure rate model for electronic products. The operation load, i.e.

For a collection of devices, it is critically important to be able to understand the expected failure rate for the devices. For the supplier of such devices, the expected failure rate will be an important indicator of future warranty liability. For the customer, the expected failure rate will be an important indicator of future satisfaction.

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.

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.
