    The rudiments of Bayesian philosophy are introduced, and the mathematics of its application are surveyed; there is no uniformity of thought concerning either. The more extreme Bayesian philosophy, which allows subjective probabilities, is a means of plausible reasoning, or of making inferences, through inductive logic. Because inferences concerning reliability concepts are important in the decisio... View full abstract»

  • Bayes' Equation, Reliability, and Multiple Hypothesis Testing

    Publication Year: 1972, Page(s):136 - 147

    The rudiments of applying Bayes' Equation to hypotheses concerning reliability are introduced in a simple manner. The application is a means of obtaining posterior probabilities, for the reliability hypotheses, which are consistent with the prior beliefs and the available test results. The posterior distributions, from which decision theory could formally arrive at optimal estimates, are greatly d... View full abstract»

  • Prior Distributions Fitted to Observed Reliability Data

    This paper describes methods of fitting prior distributions to equipment MTBF = ¿, shows the priors fitted to different equipments, establishes data criteria for fitting prior distribution to ¿, and presents the results of a robustness analysis performed on the fitted priors. Systematic procedures for fitting priors are shown for Type 1 data (number of failures in fixed time T) and Type 2 data (... View full abstract»

  • An Empirical Bayes Approach to Reliability

    A Bayesian reliability estimation technique known as the ``empirical Bayes approach'' is developed which uses previous experience nce to get a Bayesian point estimator. The techniques require no knowledge of the form of the unknown prior distribution and are robust to assumptions about its form. Empirical Bayes techniques are applicable to situations in which prior, independent observations of the... View full abstract»

  • Bayesian Decision Analysis of the Hazard Rate for a Two-Parameter Weibull Process

    Publication Year: 1972, Page(s):159 - 169
    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1759 KB)

    A two-parameter Weibull distribution is assumed to be the appropriate statistical life-model of an engineering device. The hazard rate of this device is the relevant quantity in terms of which statistical decisions are to be made. A Bayesian decision model is constructed around a conjugate probability density function for the Weibull hazard rate. Prior, posterior, and preposterior analysis of this... View full abstract»

  • Determining Optimum Burn-In and Replacement Times Using Bayesian Decision Theory

    An important problem facing a manufacturer is the determination of the amount of time to burn-in items (in order to eliminate early failures) and the age at which to replace items (to avoid failures due to wearout). This problem becomes difficult to solve if the time-to-failure distribution of an item is unknown and must be estimated from test and operational data. This paper describes a method of...

  • Bayesian Acceptance Sampling

    Publication Year: 1972, Page(s):176 - 180
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (897 KB)

    This tutorial paper shows, via an example, how optimum sampling plans can be derived using Bayesian decision theory. Both nonsequential and sequential sampling plans are described. The Bayesian method is contrasted with classical methods. The salient difference between Bayesian and classical methods is that the Bayesian approach allows one formally to pose and answer the question: ``How many shoul... View full abstract»

  • Experience with Bayesian Reliability Measurement of Large Systems

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (870 KB)

    Experience with two methods of Bayesian reliability measurement is described. An aerospace subsystem was evaluated assuming continuous gamma-distributed component failure rates. Priors were developed by conventional reliability prediction methods based on handbook data. The ``strength'' of the prior was expressed in terms of variance about a predicted mean. Comparative evaluation was also made by ... View full abstract»

  • A Personal View of the Bayesian Controversy in Reliability and Statistics

    There appear to be two important developing trends in reliability. One is away from the use of statistics by reliability engineers; the other is toward increased use of Bayesian techniques. One source of the latter may be disillusionment with what is regarded as classical statistics; however, one source of the former may be dissatisfaction with what has been called Bayesian statistics. The purpose... View full abstract»
