As an essential part in product reliability design procedure, reliability allocation can connect the reliability index between the overall product and its multiple subsystems. To obtain a reasonable reliability allocation scheme, especially for limited sample size circumstances commonly encountered in aeronautic and astronautic fields, an information fusion allocation method is constructed in the current study. Grey relational analysis (GRA) is incorporated to analyze objective data, while analytic hierarchy process (AHP) is introduced to implement subjective data analysis. Then a final allocation scheme is derived by fusion of the binary information sources. A real application regarding an aeronautic product reliability allocation is given. The sensitivity of allocation result to limited life information circumstances and comparative analysis with reference methods are implemented to demonstrate the reasonability and effectiveness.

一种考虑有限样本量情况的信息融合可靠性分配方法

作为产品可靠性设计过程中必不可少的环节，可靠性分配可以连接整个产品与其多个子系统之间的可靠性指标。为了获得合理的可靠性分配方案，特别是针对航空航天领域普遍存在的样本量有限的情况，本研究构建了一种信息融合分配方法。采用灰色关联分析（GRA）对客观数据进行分析，引入层次分析法（AHP）进行主观数据分析。然后通过融合二进制信息源得出最终的分配方案。给出了关于航空产品可靠性分配的实际应用。
