This paper presents an accuracy analysis of a suggested approximate confidence interval for system maintainability parameters. Technically, the simulation demonstrates feasible ranges of" parameter applicability for a fit of linear combinations of generated gamma variates to the gamma distribution, using the method of moments. The simulation has application to the classical confidence- interval for mean time to repair of a series system, under the assumptions of gamma distributed repair times, and method of moments estimators. The paper provides no validated conclusions although it does display parameters and ranges of apparent extremely high model validity.
