Analysing equipment failure rates

International Journal of Quality & Reliability Management, 1996
Reports on recent research at NORWEB, concerned with rationalizing the company′s equipment replacement policies which has focused on the failure rates of 11kV/415V pole mounted transformers. Results confirm that the Gumbel distribution provides a much more convincing statistical representation for these fault data than the usual Weibull option.

The Failure Rates of Mixtures

2007
Mixtures of distributions of lifetimes occur in many settings. In engineering applications, it is often the case that populations are heterogeneous, often with a small number of subpopulations. In survival analysis, selection effects can often occur.

Estimating Failure Rates and Hazard Functions

2010
This article illustrates a number of classical nonparametric and parametric procedures for estimating the failure rate (often called the hazard function) and the cumulative failure rate of non repairable units. Both point and interval estimation procedures are discussed and some graphical methods are briefly presented.

Failure rate estimation in the case of zero failures

SPIE Proceedings, 1997
When a reliability test ends in zero units having failed, traditional reliability calculations suggest that the estimated failure rate is also zero, assuming an exponential distribution. However, this is not a realistic estimate of the failure rate, as it does not take into account the number of units on test.
