摘要
先验分布的确定与表示是Bayes统计推断的出发点和关键点。针对含增长单元串并联系统的特点 ,提出了一种通过分解 综合法确定系统可靠性参数先验分布的方法。该方法有助于解决小样本复杂系统可靠性评定中无验前信息或验前历史信息较少时先验分布的确定问题 。
The confirmation of prior distribution is the beginning and key of Bayesian statistical inference. In this paper, a new method is proposed to confirm the prior distribution of reliability or reliability parameters for complex systems containing growth units based on the disassembling-synthesizing method. This method will be helpful to solve the problem of the confirmation of Bayesian inference distribution if few or even no prior information is available. Examples are given to illustrate this method.
