摘　　要：针对飞机少数装备分布无法确定的情况,文章采用随机加权法,对其可用度进行评定,当装备出现零失效的情况时,利用随机加权法对其MTBF进行评定,有效解决了可修小子样未知分布单元的可靠性评定问题,示例说明方法有较高的精度,便于工程应用。Random weighting method is used to assess availability when distribution of unit of the airplane is unknown. When unit has no failure data, Random weighting method is used to MTBF assessment. This method effectively solves the problem of reliability assessment for unknown distribution unit of the airplane and the example shows this method has a good precision and easy to engineering application.

关 键 词：可靠性评定 随机加权 可用度
