摘　　要：研究了修理有延迟且修理设备可更换的两个三状态部件和一个修理设备组成的冷贮备可修系统.假定两个部件的工作时间服从指数分布,部件发生故障后的延迟修理时间和修理时间均服从一般分布,利用Markov更新过程理论和拉普拉斯变换工具,求得了系统的可靠性指标.A cold standby repairable system with two 3-state units and a replaceable facility and delay repair is discussed. Assuming that the life of units is exponential distribution, the delay in re- pair and the repair time after their failure happening both have general distribution. By using the Markov renewal process theory and the Laplace transform tools, the reliability index of the system is obtained.
