Stochastic comparisons of coherent systems

J Navarro - Metrika, 2018 - Springer
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 …

Generalized cumulative residual entropy and record values

G Psarrakos, J Navarro - Metrika, 2013 - Springer
The Shannon entropy of a random variable has become a very useful tool in Probability
Theory. In this paper we extend the concept of cumulative residual entropy introduced by …

On negative cumulative extropy with applications

S Tahmasebi, A Toomaj - Communications in Statistics-Theory and …, 2022 - Taylor & Francis
Recently, an alternative measure of uncertainty termed by extropy was proposed by Lad et
al. Accordingly, a cumulative residual extropy is also introduced by replacing the survival …

On comparing coherent systems with heterogeneous components

FJ Samaniego, J Navarro - Advances in Applied Probability, 2016 - cambridge.org
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 …

Preservation of stochastic orders under the formation of generalized distorted distributions. Applications to coherent systems

J Navarro, Y Del Águila, MA Sordo… - … and Computing in …, 2016 - Springer
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 …

Preservation of reliability classes under the formation of coherent systems

J Navarro, Y del Águila, MA Sordo… - … Stochastic Models in …, 2014 - Wiley Online Library
The preservation of reliability aging classes under the formation of coherent systems is a
relevant topic in reliability theory. Thus, it is well known that the new better than used class is …

Minimal repair of failed components in coherent systems

J Navarro, A Arriaza, A Suárez-Llorens - European Journal of Operational …, 2019 - Elsevier
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 …

[HTML][HTML] Copula-based representations for the reliability of the residual lifetimes of coherent systems with dependent components

J Navarro, F Durante - Journal of Multivariate Analysis, 2017 - Elsevier
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 …

Orderings of coherent systems with randomized dependent components

J Navarro, F Pellerey, A Di Crescenzo - European Journal of Operational …, 2015 - Elsevier
Consider a general coherent system with independent or dependent components, and
assume that the components are randomly chosen from two different stocks, with the …

Preservation of ILR and IFR aging classes in sums of dependent random variables

J Navarro, F Pellerey - Applied Stochastic Models in Business …, 2022 - Wiley Online Library
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 …
