| 摘 要： | 考虑可修的串联系统,其单元产品在出现故障时,由于种种原因,故障不能得到及时维修,形成了一段保障延误时间.于是这一更新过程为:正常工作(直到出现故障)-保障延误-故障维修-正常工作…….假设每一时段的分布未知,且相互独立,给出了可用度的点估计和置信下限. |
| 关 键 词： | 可用度 置信下限 分布自由估计 |

| Abstract: | Consider a repairable system in series in which, for some reasons, individual units cannot get repaired in time after failure occurs, thereby creating a period of delayed maintenance. Thus, this process of renewal becomes a cycle that alternates in sequence between up time (normal operation until failure occurs), maintenance delay, failure repair and up time again. Suppose the distributions of these successive periods are free and are independent of one another, then the point estimation and lower confidence limit of availability can be obtained. |
| Keywords: | availability lower confidence limit distribution free estimation |
