摘要
在某些文献中,仅讨论了系统的平均寿命,并据此选择最佳可靠性系统,这是不完善的。本文研究系统寿命的均值和方差,并设计出较为理想的可靠性系统。
In some references, only the mean time to failure of a system is discussed and the system with optimal reliability is selected. It is not completed. In this paper, we consider both the mathematical expectation and variance for the time to failure of some systems and design a system with ideal reliability.
