摘要
文中给出了由小样本试验数据确定船体结构疲劳寿命分布的Bayes方法。采用二级模糊综合评判获得先验概率 ,通过似然函数反映样本信息 ,利用Bayes定理综合先验信息与样本信息得到后验概率。将统计推断建立在后验概率的基础上 ,弥补了传统方法在统计推断上的缺陷。
This paper introduces the Bayesian method to determine fatigue life reliability model of ship structure by using small samples.The statistics inference is based on the after probability which got through using the Bayesian method to synthesize the first probability and the samples.
