Item A new extended δ-shock model with the consideration of shock magnitude(Applied Stochastic Models in Business and Industry, 2024-07-14) Lorvand, Hamed; Eryılmaz, SerkanIn this article, a new -shock model that takes into account the magnitude of shocks is introduced and studied from reliability perspective. According to the new model, the system breaks down if either a shock after non-critical shock occurs in a time length less than or a shock after a critical shock occurs in a time length less than where . The distribution of the system's lifetime is studied for both discrete and continuous intershock time distributions. It is shown that a new model is useful to describe a certain cold standby repairable system.Article On 𝜹-shock model with a change point in intershock time distribution(Statistics & Probability Letters, 2024-06-25) Chadjiconstantinidis, Stathis; Eryılmaz, SerkanIn this paper, we study the reliability of a system that works under 𝛿-shock model. That is, the system failure occurs when the time between two successive shocks is less than a given thresh old 𝛿. In a traditional setup of the 𝛿 shock model, the intershock times are assumed to have the same distribution. In the present setup, a change occurs in the distribution of the intershock times due to an environmental effect. Thus, the distribution of the intershock times changes after a random number of shocks. The reliability of the system is studied under this change point setup.Article Reliability and performance evaluation of weighted k-out-of-n:G system consisting of components with discrete lifetimes(Reliability Engineering and System Safety, 2024-08-31) Eryılmaz, SerkanFor the k-out-of-n system consisting of components that have di§erent weights, the system is in a good state if the total weight of working components is at least k. Such a system is known to be weighted k-out-of-n:G system. Although the weighted k-out-of-n system that has continuously distributed componentsílifetimes has been extensively studied, the discrete weighted k-out-of-n:G system has not been consid ered yet. The present paper Ölls this gap by modelling and analyzing the weighted k-out-of-n:G system that consists of discretely distributed componentsílifetimes. In particular, the behavior of the total capacity/weight of the system with respect to the component failures is evaluated. An optimization problem that is concerned with the determination of optimal number of spare components is also formulated by utilizing the mean lost capacity of the system.
