Abstract : The Office of the Manager, National Communications System (OMNCS) has developed a systemlevel approach for estimating the effects of HighAltitude Electromagnetic Pulse (HEMP) on the connectivity of telecommunications networks. This approach incorporates a Bayesian statistical model which estimates the HEMPinduced failure probabilities of telecommunications switches and transmission facilities. the purpose of this analysis is to address the sensitivity of the Bayesian model. This is done by systematically varying two model input parametersthe number of observations, and the equipment failure rates. Throughout the study, a noninformative prior distribution is used. The sensitivity of the Bayesian model to the noninformative prior distribution is investigated from a theoretical mathematical perspective. Keywords: probability density functions; cumulative distribution functions; statistical models.
