Abstract: This paper presented the estimation of system reliability using two parameter Weibull distribution. The parameters are estimated using Weibull probability plot & statistical analysis and the results being presented in charts. An increasing complexity of systems often leads to an increase of failure mechanisms. A statistical analysis of the lifetime of systems with several failure mechanisms consisting of several subcomponents considered The Weibull distribution is commonly used as a lifetime distribution in reliability applications. The two-parameter Weibull distribution can represent a decreasing, constant or increasing failure rate.
