Abstract:

Following a complete discussion of the problems associated with the definition and quantification of maintainability, it is argued that maintainability is not the equipment parameter to be specified and achieved without regard to other performance parameters. It is proposed in this thesis that inherent availability is the critical parameter to be specified and met by an aircraft weapon system contractor. It is further proposed that a series of availability tests be conducted to reflect a progressively decreasing consumers risk and allow for increased system performance resulting from increased human experience and engineering improvements. A sequential sampling plan is designed for an exponential or a Weibull distribution of times-between-maintenance and times-to-repair. A hypergeometric sampling plan is presented for use in testing the operational readiness of the test fleet for any given proposed squadron size. Author
