摘要
针对装备平均修复时间总体分布模型具有模糊性和试验具有继承性的特点,应用了贝叶斯理论和模糊数学思想,以研制性试验维修样本为验前信息,通过构建二级模糊综合评判模型获得平均修复时间分布的验后概率,进而确定了平均修复时间所属的总体分布模型.通过工程实例分析,验证了方法的有效性.
The collectivity distribution model of mean time to repair for equipment has the characters of fuzziness and inheritance.Firstly,based on Bayesian theory and fuzzy theory,prior information is established by making use of maintenance sample in development test.Posterior probability of mean time to repair is obtained by using two grade model of fuzzy synthesis evaluation.Finally,the collectivity distribution model of mean time to repair is confirmed.The validity of this method discussed formerly is proven by ...
