摘要：

This paper presents a stable technique for obtaining the maximum likelihood estimate of Weibull parameters of the life distribution of two components that form a series system. The technique explained here requires much more computation than a previously published procedure. The simulation results, however, show the standard deviation of the estimated values of the Weibull parameters greatly reduced. This technique does not require the concomitant indicator, and can be applied not only for complete data but for randomly censored data.
