摘要
为了进行有效的预先维修保障,合理的可靠性模型十分必要。针对某型特种设备数量少,先验信息不足的特点,将Bayes BootStrap方法应用于某型航海特种设备的可靠性模型参数的确定,给出了该方法的基本原理以及实现步骤。并结合某型航海特种设备小样本试验数据,计算了维修时间概率密度函数、修复率函数、平均修复时间、最大修复时间等,验证了本方法的可行性。
For effectively advance repair, reasonable reliability model is very necessary. Because of the limitations of special equipment quantity and priori information, Bayes BootStrap method is applied to a certain type of marine equipment reliability model to determine the parameters , basic principle of the method and steps are given out. And combined with small sample test data of certain type marine special equipment, repair time probability density function, repair rate function, mean time to repair, the maximum time to repair, are calculated to verify the feasibility of the method.
