Dynamic Reliability and Performance Evaluation of Multi-State Systems With Two Components
(Hacettepe Univ, Fac Sci, 2011) Eryilmaz, Serkan; Industrial Engineering
In this paper we study multi-state systems consisting of two components when the number of system states and the number of states of each component are the same, i.e. the systems under consideration are homogeneous multi-state systems. In particular we evaluate multi-state series and cold standby systems assuming that the degradation in their components follow a Markov process. The behaviour of systems with respect to degradation rates is also investigated in terms of stochastic ordering.

Dynamic Reliability Evaluation of Consecutive-K System
(Taylor & Francis inc, 2011) Eryilmaz, Serkan; Kan, Cihangir
A consecutive k-within-m-out-of-n:F system consists of n linearly ordered components and fails if and only if there are m consecutive components which include among them at least k failed components. This system model generalizes both consecutive k-out-of-n:F and k-out-of-n:F systems. In this article, we study the dynamic reliability properties of consecutive k-within-m-out-of-n:F system consisting of exchangeable dependent components. We also obtain some stochastic ordering results and use them to get simple approximation formulae for the survival function and mean time to failure of this system.
