广义NBUT寿命分布及其封闭性质

Some Properties of Generalized NBUT Lifetime Distribution

利用广义试验总时间变换序,给出了广义NBUT(简记为GNBUT)寿命分布的概念,讨论了GNBUT寿命分布与NBUT寿命分布的关系.进一步给出了GNBUT寿命分布在构成串联系统和随机小下的封闭性质.

Based on the generalized total time on test transform order, a new lifetime distribution named generalized NBUT（ GNBUT） is established. Relationship between the GNBUT lifetime distribution and the NBUT lifetime distribution are discussed. It is found that the implications are closely related to the IFR or DFR property of the referred life distribu-tion G. Preservation of the GNBUT is also developed by taking the minima.
