CConsider an automated security test $($e$.$g$.,$ explosives$-$scanning$)$ station for checked baggage at CVG$,$ the Cincinnati$-$Northern Kentucky airport. The test workstation is composed of a single machine that has a base$-$case test capacity of $5$ bags per minute. $($It takes on average $\mathrm{.}20$ minutes to process a bag.$)$ The squared coefficient of variation, SCV$,$ of the base processing time of the test operation is $0\mathrm{.}5625,$ making the standard deviation equal to $0\mathrm{.}15.$ The machine is subject to random failure with mean time to failure $($MTTF or uptime$),$ mf $=7$ hours and mean time to repair $($MTTR or downtime$),$ mr $=40$ minutes. The repair time is exponentially distributed with SCV$,$ cr$2=1.$
