复杂电子系统中各单元结构具有不同的分布类型,且检验项目中存在大量的无失效数据,使得系统的可靠性评估非常困难。针对无失效系统可靠性分析的特点,提出了基于Bayes方法、多源信息融合的可靠性评估方法,将各单元信息混合折算为成败型信息,建立了潜在失效状态可靠性分析模型,合理地利用验前信息,使计算结果具有更强的功效性。
The structure of each unit in a complex electronic system has different distribution types, and there is a large amount of non-failure data in the test items, which makes the reliability evaluation of the system very difficult. According to the characteristics of reliability analysis of non-failure system, this paper proposes Bayes method and reliability assessment method based on multi-source information fusion. The information of each unit is converted into success or failure information, and the reliability analysis model of potential failure state is established. Pre-test information, the calculation results have more effectiveness.
