Atwood, C L

In Vesely's binomial failure rate model, a system of m components is hit by random shocks which may cause components simultaneously to fail, each component with equal probability. Individual components may also fail when no shock has occured. The data possibilities considered are those causes of single failures that are identifiable (as shock or not) or not identifiable. Given data from such a system, non-Bayesian and Bayesian point and interval estimators are found for the various quantitites of interest. Residual analyses and hypothesis tests are presented for checking the model assumptions. An example is worked out.
