【摘要】 通常航空电子产品的可靠性评估属于小样本问题,需要采用Bayes方法以便充分利用专家经验等先验信息才能获取可信的评估结果。而可靠性工程专家习惯于将自己的意见用模糊信息来表达,普通Bayes方法不易处理这些模糊先验信息,针对这种情况提出了一种新的Bayes可靠性评估策略,很好地综合了模糊专家意见和样本数据。更多还原

【Abstract】 Bayesian method is widely used in reliability assessment of electronic product in aviation when test data is small scale.It can improve the reliability of the result for making use of prior information such as ex- pert judgment.But general Bayesian method is hard to deal with expert judgment when it is fuzzy.Then a new method is proposed in this paper,it can synthesize the fuzzy expert opinion and the sample data in a good manner.更多还原
