The study of stochastic comparisons of coherent systems with different structures is a
relevant topic in reliability theory. Several results have been obtained for specific …

The present work studies the effect of redundancies on the reliability of coherent systems
formed by modules. Different redundancies at components' level versus redundancies at …

In this paper we investigate different methods that may be used to compare coherent
systems having heterogeneous components. We consider both the case of systems with …

The preservation of stochastic orders under the formation of coherent systems is a relevant
topic in the reliability theory. Several properties have been obtained under the assumption of …

The minimal repair replacement is a reasonable assumption in many practical systems.
Under this assumption a failed component is replaced by another one whose reliability is the …

In the context of coherent systems, we obtain representations for the reliability function of the
residual lifetime at time t under different assumptions. Specifically, four cases are considered …

Consider a general coherent system with independent or dependent components, and
assume that the components are randomly chosen from two different stocks, with the …

Closure of aging classes with respect to sums is a relevant topic in different areas of applied
probability. In the case of independent random variables (ie, for convolutions) this …

A distribution function F is a generalized distorted distribution of the distribution functions
F_1, ..., F_n F 1,…, F n if F= Q (F_1, ..., F_n) F= Q (F 1,…, F n) for an increasing continuous …

Aging tendency of items and compound structures is an important and challenging subject of
the lifetime analysis. This phenomenon attracts the attention of an increasing number of …
