A Class of Shock Models for a System That Is Equipped with a Protection Block with an Application To Wind Turbine Reliability
(John Wiley and Sons Ltd, 2025) Eryilmaz, S.; Industrial Engineering; 06. School Of Engineering; 01. Atılım University
This paper studies a class of shock models for a system that is equipped with a protection block that has its own failure rate. Under the considered class, the system exposed to shocks at random times is protected by the protection block, and the probability of the shock damaging the system varies depending on whether the protection block operates or not. The system failure criteria is defined based on the pattern of the critical/damaging shocks. Exact expressions for the reliability and mean time to failure of the system are obtained, and detailed computations are presented for the run shock model, which is included in the class. The application of the extreme shock model, which is included in the relevant class, to wind turbine reliability is also discussed. © 2025 John Wiley & Sons Ltd.

On the Mean Residual Lifetime of Consecutive K-Out Systems
(Springer, 2012) Salehi, E. T.; Asadi, M.; Eryilmaz, S.; Industrial Engineering; 06. School Of Engineering; 01. Atılım University
In recent years, consecutive systems were shown to have many applications in various branches of science such as engineering. This paper is a study on the stochastic and aging properties of residual lifetime of consecutive k-out-of-n systems under the condition that n-r+1, ra parts per thousand currency signn, components of the system are working at time t. We consider the linear and circular consecutive k-out-of-n systems and propose a mean residual lifetime (MRL) for such systems. Several properties of the proposed MRL is investigated. The mixture representation of the MRL of the systems with respect to the vector of signatures of the system is also studied.

Reliability Analysis of Consecutive k-out-of-n< Systems With Non-Identical Components Lifetimes
(Elsevier Science Bv, 2011) Salehi, E. T.; Asadi, M.; Eryilmaz, S.; Industrial Engineering; 06. School Of Engineering; 01. Atılım University
In recent years, the study of reliability properties of consecutive k-out-of-n systems has attracted a great deal of attention from both theoretical and practical perspectives. In this paper we consider linear and circular consecutive k-out-of-n systems. It is assumed that lifetimes of components of the systems are independent but their probability distributions are non-identical. We study the reliability properties of the residual lifetimes of such systems under the condition that at least (n - r + 1), r <= n, components of the system are operating. We also investigate the probability that a specific number of components of the above-mentioned system operate at time t, t > 0, under the condition that the system is alive at time t.

Reliability of Weighted k-out-of-n< g Systems Consisting of Two Types of Components and a Cold Standby Component
(Taylor & Francis inc, 2017) Franko, C.; Eryılmaz, Serkan; Tutuncu, G. Y.; Eryilmaz, S.; Eryılmaz, Serkan; Industrial Engineering; Industrial Engineering; 06. School Of Engineering; 01. Atılım University
In this article, the influence of a cold standby component to the reliability of weighted k-out-of-n: G systems consisting of two different types of components is studied. Weighted k-out-of-n: G systems are generalization of k-out-of-n systems that has attracted substantial interest in reliability theory because of their various applications in engineering. A method based on residual lifetimes of mixed components is presented for computing reliability of weighted k-out-of-n: G systems with two types of components and a cold standby component. Reliability and mean time to failure of different structured systems have been computed. Moreover, obtained results are used for defining optimal system configurations that can minimize the overall system costs.
