Description/Abstract | Consider the case of a single test unit which must be tested at some level of test stress.^Suppose that the test stress level is free to be determined, and that only the survival or nonsurvival of the unit is observed.^It is assumed that the unit is designed to withstand a known and specified design stress level.^A Bayesian model is developed for determining the required level of test stress which maximizes the expected probability of survival at the design stress level.^Engineering experience from similar past tests on similar units is used to fit the model.^A practical application illustrates the method.^The sensitivity of the procedure to changes in the parameters used in fitting the model is also examined. |
