This paper studies the uncertainties of component reliability parameters and their impact on system lifetime distribution. Monte Carlo simulation was applied to investigate the correlation between the system complexity and its Weibull shape parameter when component reliability parameters are estimated with uncertainties. Results show the system lifetime approaches the exponential distribution when the number of components becomes large.
