【Abstract】 In this paper, the reliability index of cold standby system under the timing truncation experimental data is evaluated by means of generalized approximate confidence limit and E-Bayes methods. Therefore, the generalized method of approximate confidence limits and the E-Bayes approximate confidence limit of the system reliability are obtained. The simulated result of Monte-carlo method indicates that E-Bayes method under small samples has significant advantages over the generalized approximate confidence limit, while under large samples the result is on the contrary.更多还原
