| 摘 要： | 本文讨论了部件和系统都作定数截尾试验时,独立指数部件串联系统可靠度的置信限估计问题。推广了中的结果,得到了结合部件试验数据和系统试验数据的系统可靠度精确置信下限求解方程。由此解得的可靠度置信限在无偏意义下是最优的。

| Abstract: | This paper gives a very accurate and uniformly-unbiased confidence bound of series system reliability for both component life-testing data and system life-testing data.The system is a series system of K independent components whose surviving time under- goes exponential distribution.The life-tests of both the system and the components are assumed to be fixed failure numbers,i.e.,n components are tested and the tests continue until r'th failure is found. |

| Keywords: | statistics system reliability exponential distribution confidence lower limit failure number |
