Bayes life-time tests with imprecise input information
The problem of the Bayes estimation of the failure rate is considered when the reliability data are presented in a vague form. It is also assumed that the prior information about the estimated failure rate is given in the form of the gamma distribution with imprecisely defined parameters. Fuzzy sets are used to model the lack of precision. The formulae are given for the fuzzy Bayes estimator of the failure rate.
