A Simulation Study of Methods for Estimating Availability for Exponentially Distributed Operating Times and Log-normally Distributed Repair Times.
Abstract
This study seeks to determine the superiority of various methods for estimating intrinsic availability from demonstration test with equal numbers of operating times and repair times. A total of 31 methods are investigated. The parameters used to simulate availabilities are for exponentially distributed operating times and log-normally distributed repair times and are in a range that is of interest to users of modern weapon systems. The conclusion is reached that no advantage is possible for one estimating procedure as opposed to another. As a result of the knowledge gained in this study, a set of confidence graphs useful for designing availability tests were constructed.
