Failure-Rate Prediction and Wearout Detection,

Abstract

The paper is divided into four specific technical sections. The first presents two classical approaches to the detection of the commencement of wearout of a device, the primary one being the F technique. These methods are essentially ones for testing for constantness in the failure rate and as such can therefore also be used to detect the end of burn-in. The use of the F procedure is then illustrated on some Navy data. The second technical section presents a Bayes-type approach to the same problem and illustrates its use via a similated problem. The next two sections get back to more classical methods, with the first outlining some direct approaches to the estimation of the hazard-rate function itself, and the second indicating a simple method for incorporating the estimating procedure into the determination of an optimal economic replacement interval.
