| Popis: | The efficiency of a Weibull demonstration test plan is completely determined by the total experimental time (Ta), which depends on the unknown sample size (n) and on the Weibull shape parameter (beta). Thus, once beta was selected, Ta depends only on n. Unfortunately, because n was estimated by the parametrical binomial approach, then if the confidence level C was higher than 0.63, n, and as consequence Ta, was overestimated, (For C |
