正态型元件贮备系统可靠性近似Fiducial置信限

The Approximate Fiducial Lower Confidence Limit of the Reliability for Standby System of Normal Type Components

设系统Ａ为Ｋ个独立的元件Ｂ１，Ｂ２，…，Ｂｋ和一个转换开关组成的贮备系统，设第ｉ个元件的寿命服从参数μ，σ２的正态分布，参数μ，σ２均未知。设转换开关为成败型元件，可靠性Ｐ，参数Ｐ或已知或未知。

Suppose the standby system A is composed of in dependent components B 1,B 2,…,B k and a switch.Suppose the life Y i of the component B i has Normal distribution N(μ,σ 2),parameters μ,σ 2,are unknown, i=1,2,…,k.Suppose the swith is a pass fail component,the reliability of swith,p,is known (or unknown). In this paper, we discuss the approximate Fiducial lower confidence limit of the standby system.
