Abstract
This paper presents a stable technique for obtaining the maximum likelihood estimator of parameters of exponential distribution
of M components that form 1) series system 2) parallel system and 3) s out of M:G system. The data consists of lifetime of the system only,
that it is not known which component caused the system failure and can be applied not
only for complete data but for randomly censored data also. The log likelihood function presented can be used for the estimation
of two parameter Weibull distribution in all the three cases.
Keywords: Maximum likelihood estimator-Exponential distribution-Reliability models-iterative method.
