关于独立不同分布元件构成的协同系统剩余寿命和休止时间的混合表达

On mixture representation of residual lifetime and inactive time of the coherent system with independent but not identical components

建立了由独立不同分布元件构成的协同系统剩余寿命和休止时间的两个混合表达式,基于该混合表达式中系数向量的随机序性质,得到了具有不同结构和不同元件寿命的两个协同系统剩余寿命和休止时间的一些随机序性质.

Two mixture representations of residual lifetime and inactive time of the coherent system with independent but not identical components were established. Based on the stochastically ordered coe？cient vectors of mixture representations, some stochastic ordering properties for the residual lifetime and inactive time of two coherent systems having different structures and different component lifetimes were obtained.
