Virtual Bookstore Citation Title SEQUENTIAL TESTING OF HYPOTHESES CONCERNING THE RELIABILITY OF A SYSTEM MODELED BY A TWO-PARAMETER WEIBULL DISTRIBUTION. Author(s) Lussier,Philippe A. ; Corporate Author(s) AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH SCHOOL OF ENGINEERING Report Date 12/1/1981 Page Count 55 Abstract 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.
