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

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

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。

Under the assumptions that the lifetime and maintenance time of components follow exponential distri- bution, 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.
