基于剩余寿命的寿命分布的几个新的偏序

摘要

As a supplement to the existing literature, some new partial orderings of life distributions with respect to aging properties DMRL, NBUC, IFR(2) and NBU(2) are proposed in order to make a comparison between two arbitrary life distributions. Implications among them are established so that they are embedded into the chain of the known ones in existence and some of their properties are also investigated.%基于剩余寿命函数,建立了利用寿命分布的几个新的偏序以度量年龄性质DMRL,NBUC,IFR(2),NBU(2)的程度,并讨论它们同已有的年龄性质的偏序之间的关系.
