n个同型部件k个修理设备的冷贮备可修系统的可靠度研究

在设定元件的工作寿命和维修时间的分布都是负指数分布,全部随机变量都互相独立,发生故障的元件能够修成新的前提下,对由n个同种型号的元件和k(k≤n)个设备修理构成的冷贮存可修体系的可靠性方面进行分析,构建关于此体系的数学模型,获得了n个同种型号元件的冷贮存体系在k个设备修理的情况下的可靠度,且探讨在修理设备k值不相同的情况的可靠度,并针对n=3的情况下,分析修理设备数不相同情况下的可靠度。

Study on Reliability of Cold Standbys Repairable System with n Identity artsand k Repair Equipment

Under the assumptions that the lifetime and maintenance time of components follow exponential distribution,all random variables are considered independent of each other. The reliability analysis is obtained to study a kind of cold standby repairable system with n components of the same type and k(kn) repair facilities. After the system model is built, the reliability of cold standby system can be computed and discussed under different k value. Finally, the reliability of different k value can be analysised for n=3.
