Limited failure-censored life test for the Weibull distribution

When the distribution of lifetimes is 2-parameter exponential, Balasooriya [6] provided a failure-censored reliability sampling-plan to save test time. This paper extends the Balasooriya sampling plan to the Weibull distribution and provides a limited failure-censored reliability sampling plan (LFCR) to do life testing when test facilities are scarce. The -expected test time of the LFCR is computed, and the optimal stopping rule of LFCR corresponding to the shortest test time is established. The -confidence intervals for the parameters are generated.
