研究两个不同型部件、两个修理工组成的冷贮备可修系统。假定部件寿命服从一般分布，维修时间服从指数分布，利用马尔可夫更新过程方法和拉普拉斯变换工具，得到了系统有关首次故障前时间分布、可用度和故障频度等可靠性指标的表达式。
关 键 词 冷贮备; 马尔可夫; 更新方程; 可靠性
Abstract This paper considers a cold standby repairable system consisting of two dissimilar units and two repairmen. In the system, the life distributions of the two units are assumed to be the general distribution, but the repair distribution to be the exponential . By using the non-markov renewal process and the tool of the Laplace transform, we obtain some reliability quantities of the system,such as the distribution of the first failure, the availability and the frequency of failure of the system, etc.
Key words cold standby; markov; renewl equation; reliability
