Abstract : Test Method Three of Military Standard-471 is a maintainability demonstration test plan which demonstrates the achievement of a specified equipment repair time. This test plan was designed to be used when the distribution of corrective maintenance task times is lognormal. The report will conduct Test Method Three using simulated data from the Weibull distribution. Operating characteristic curves will be constructed to determine the sensitivity of Test Method Three to a Weibull distribution. The analysis concludes that there is a slight change in the alpha and beta risk when the distribution of corrective maintenance times fit the particular Weibull distributions presented in the report. However, the alpha and beta risk vary drastically when the specified equipment repair time is not selected according to the requirement of the test. (Author)
