| 中文摘要: |
| 考虑一个两个交替运行部件冷储备系统的可靠性，系统每过T时间部件交替运行一次，部件的寿命和维修时间服从一般分布，所有随机变量相互独立，利用马尔科夫更新过程方法以及L S变换工具，得到了系统主要可靠性指标的拉普拉斯变换表达式，系统的平均首次故障前时间, 系统的稳态可用度,系统的稳态平均故障频度。 |
| 英文摘要: |
| In this paper, the reliability of cold standby repairable system with two alternate run units is discussed. In the system, unit alternatively runs every T time. The lifetime and the repair time of units are assumed to be of general distribution. All random variables are independent. The L S transform expressions of primary reliability indexes of the system, the expected time of the system to first failure, the steady availability of system, and the steady expected frequency of failures of the system are obtained by using the Markov renewal process method and the tool of the LS transform. |
