摘要
在文[1]的基础上,本文研究了修理有延迟和修理设备可更换的两单元冷储备可修系统.在假定单元的寿命服从指数分布、修理时间和延迟时间服从一般分布、修理设备的寿命和故障后的更换时间服从指数分布下,通过定义修理设备的"广义忙期",使用更新过程理论和全概率分解技术,提出一种新的分析技巧,讨论了修理设备的一些可靠性指标,获得了如修理设备的可用度和故障次数等可靠性结果.
Based on paper [1], this paper considers some reliability quantities of the repair facility in the two-unit same cold standby repairable system with a replaceable repair facility and delay repair, in which the failure time of unit is assumed to follow exponential distribution, and the repair time and delay time of failed unit are assumed to follow arbitrary distributions, whereas the failure and replacement time distributions of the repair facility are exponential and arbitrary. The generalized busy period of the repair facility is defined, and a new approach to analysis the reliability quantities of the repair facility are presented by using renewal process theory and total probability decomposition. Some reliability results, such as availability and failure number, are obtained.
