基于继承因子的冷贮备串联系统可靠性估计

冷贮备串联系统在可靠性工程中有着广泛的应用。文章以冷贮备串联系统为背景,在混合先验分布的情形下,研究了冷贮备串联系统的可靠性估计问题。其中继承因子的引入,既体现了新产品对于老产品的继承性,同时又体现了新产品由于研制改进而带来的不确定性,综合地考虑了产品在设计和改进中的信息。最后,基于非对称损失函数-LINEX损失函数,给出了冷贮备串联系统失效率、可靠度及平均寿命的Bayes估计。

Reliability Assessment for Cold Standby Series System of Inheritance Factor

Cold standby series system is widely used in engineering.Based on mixed distribution,the problems of estimating the reliability performances for cold standby series system are studied.The concept of inherit factor is introduced,which includes both their inheritance and their difference between the new and the old products,and various information during product design and improvement is comprehensively considered.At last,under the asymmetric loss functions-LINEX loss function,the formulae to calculate Bayes estimation of the failure rate,the reliability function and mean life time are given.
