Monte Carlo Analysis techniques are used for the development of testplans concerning hypothesized system reliabilities. Systems under considerationare those in which component failure rates are best described by the two-parameter Weibull probability density function. The statistical test employed isWald's sequential probability radio test using independent, asymptoticallycomputed variances (Cramer-Rao Lower Bound Technique). The null hypothesis, HO:HO: RO =.90, is tested against alternative reliabilities of .854, .810, and .729. Three pairs of alpha and beta risk levels are considered for each test ((.1,.1), (.2,2), (.1,.2). A truncation decision for the sequential test is made at1.5 times the fixed sample test size for the same conditions. One thousand MonteCarlo repetitions are used for these test procedures. (Author)
