串联和并联系统元件的可靠性估计:威布尔模型

Reliability estimators for the components of series and parallel systems: The Weibull model

Felipe L. Bhering, Carlos A. de B. Pereira, Adriano Polpo

摘要:

本文提出了一种分层贝叶斯方法来估计元件的可靠性(生存),使用威布尔模型,他们每个人。由于串联(并联)系统中元件可靠性的估计等价于右(左)删失数据下元件生存函数的估计,因此该方法可用于一般生存删失数据下元件可靠性的估计。除了威布尔参数模型的可靠性数据,独立的Γ分布被认为是在第一层次的威布尔参数和独立的均匀分布在实数线作为先验的伽玛参数。为了评估模型,一个例子和模拟研究进行了讨论。

英文摘要:

This paper presents a hierarchical Bayesian approach to the estimation of components' reliability (survival) using a Weibull model for each of them. The proposed method can be used to estimation with general survival censored data, because the estimation of a component's reliability in a series (parallel) system is equivalent to the estimation of its survival function with right- (left-) censored data. Besides the Weibull parametric model for reliability data, independent gamma distributions are considered at the first hierarchical level for the Weibull parameters and independent uniform distributions over the real line as priors for the parameters of the gammas. In order to evaluate the model, an example and a simulation study are discussed.
