简介:【摘要】本文基与Bayes理论,采用了Bayes点估计的方法对可靠性数据进行处理,针对某导弹武器系统战斗工作可靠度评估方法,对MML进行改进,得到基于Bayes理论的战斗工作可靠度评估方法。并将结果与传统的直接评估法和综合评估法中的CSMR法作对比。
简介:为消除Bayes动态模型中噪声的正态性假定对模型的实用性的限制,在Bayes整体风险最小的准则下,建立了非正态Bayes动态模型状态参数向量纳向前m步Bayes最优线性预洲及其风险矩阵的循环递推方程,使正态Bayes动态模型的相关结果成为其特例。该方法可以在较大程度上拓宽Bayes动态模型及其Bayes预测的适用范围,有一定纳理论意义和实用价值。
