Chapter 23 Weibull Prediction Limits for a Future Number of Failures Under Parametric Uncertainty

摘要

Results of research about the prediction of random quantities have enormous potential for application in engineering and are, indeed, of fundamental importance, which is revealed when one addresses the question: if in a system with m components, k quantities failed in the time interval [0, t_1], how many components will fail in a given future time belonging to the interval [t_1,t_2]? or, even more, what are the prediction limits (lower and upper) for the number of components that will fail in the time interval [t_1, t_2]? There are many systems in which the prediction of times of failure of parts is critical.
