We consider two classes of life distribution, VD and V I, the members of which are defined in terms of the conditional variance σ2(t) of the remaining lifetime of a system: a life distribution F belongs to VD if σF2(t) is a decreasing function and to VI if σF2(t) is increasing. We study closure properties of these classes under relevant reliability operations such as mixing, convolution and formation of coherent systems. We show, for example, that the class VD is not closed under convolution or mixing, and that the class VI is not closed under formation of coherent systems. © Applied Probability Trust 2004.
