Consecutive k-out-of-n:F Systems Have Unbounded Roots

Marilena Jianu, Leonard Daus, Vlad-Florin Dragoi +1

This article is studying the roots of the reliability polynomials of linear consecutive-\textit{k}-out-of-\textit{n}:\textit{F} systems. We are able to prove that these roots are u…

Generalized Convexity Properties and Shape Based Approximation in Networks Reliability

Gabriela Cristescu, Vlad-Florin Dragoi, Sorin-Horatiu Hoara

Some properties of generalized convexity for sets and for functions are identified in case of the reliability polynomials of two dual minimal networks. A method of approximating th…

Tight Bounds on the Coeffcients of Consecutive -out-of-: Systems

Vlad-Florin Drăgoi, Simon R. Cowell, Valeriu Beiu

In this paper we compute the coefficients of the reliability polynomial of a consecutive--out-of-: system, in Bernstein basis, using the generalized Pascal coefficients. B…

Cubic spline approximation of the reliability polynomials of two dual hammock networks

Gabriela Cristescu, Vlad-Florin Drăgoi

The property of preserving the convexity and concavity of the Bernstein polynomial and of the Bézier curves is used to generate a method of approximating the reliability polynomial…

Fast Reliability Ranking of Matchstick Minimal Networks

Vlad-Florin Dragoi, Valeriu Beiu

In this article, we take a closer look at the reliability of large minimal networks constructed by repeated compositions of the simplest possible networks. For a given number of de…
