基于修理工多重休假的线性相邻n-1/n(G)可修系统的研究

Analysis of Repairable System with Repairman Vacation Based on A Consecutive n-1-out-of-n:G

研究了修理工具有多重延误休假规则的线性相邻n-1/n(G)可修系统.假定部件寿命、修理工延误休假时间均服从指数分布,部件修理时间、修理工休假时间均服从一般分布,利用补充变量法和拉普拉斯变换工具,得到了此系统的可靠度、首次平均故障前平均时间等可靠性指标的精确表达式.结论表明,文中讨论的模型比以往的模型更具一般性.

A consecutive n-1-out-of-n ：G repairable system with repairman vacation was studied.Assuming that the components＇ lifetimes and the delay vacation time of the repairman are both exponentially distributed,and repair times of the components and vacation times of repairman are both generally distributed,the exact formulas of the reliability and MTTFF of the system were obtained using the supplementary variable technique and the tool of Laplace transform.The results of this model are more general than those of the previous.
