摘　　要：针对航空电子设备的研制阶段和数据特点,研究了一套跨阶段、变母体、小子样数据条件下的多源信息融合的可靠性评估模型。该模型基于Bayes方法融合样本信息和先验信息,通过后验信息和观测数据对先验信息进行更新,并利用马尔可夫链蒙特卡洛(MCMC)方法进行求解,提高了航空电子装备的可靠性评估的拟合优度,使得估计结果更接近于真实情况。Aiming at the development stage and data characteristics of avionics equipment,a reliability evaluation model of multi-source information fusion in the context of cross-stage,variable population,and small sample data is studied.In this model,the Bayes method is adopted to integrate sample information and prior knowledge,and the prior information is updated through posterior information and observation data.Additionally,the MCMC method is used to solve it,which enhances the goodness of fit in evaluating the reliability of avionics equipment,and makes the estimated results closer to the real situation.
