New Weibull Handbook

Weibull analysis is the world's most popular method of analyzing and predicting failures and malfunctions of all types. The method identifies the category of failure: infant mortality, random or wear out. Weibull analysis provides the quantitative information needed for making RCM decisions which are often made from a qualitative approach. Weibull failure predictions are accurate even with very small samples of data. Weibull analysis calculates optimal parts replacement intervals for minimizing cost. Weibull analysis is needed for making risk based inspection decisions to take action or defer action on potential failures. The most accurate warranty claims predictions are based on Weibull analysis. Weibayes, invented by Dr. Abernethy and others at Pratt & Whitney Aircraft, provides the most accurate analysis for small samples and Weibayes substantiation tests are the most cost effective compared to all other types of tests. Wherever there are alternative methods like likelihood ratio versus Fisher Matrix versus Pivotal confidence methods or maximum likelihood versus median rank regression, best practices are indicated. This is a unique feature of The New Weibull Handbook.
