    Joint Reliability Importance in Coherent Systems With Exchangeable Dependent Components
    (Ieee-inst Electrical Electronics Engineers inc, 2016) Eryilmaz, Serkan; Oruc, Ozlem Ege; Oger, Volkan
    In this paper, a general formula for computing the joint reliability importance of two components is obtained for a binary coherent system that consists of exchangeable dependent components. Using the new formula, the joint reliability importance can be easily calculated if the path sets of the system are known. As a special case, an expression for the joint reliability importance of two components is also obtained for a system consisting of independent and identical components. Illustrative numerical results are presented to compare the joint reliability importance of two components in the bridge system for the two cases when the components are exchangeable dependent and when the components are independent and identical.

    Joint Reliability Importance in Linear m-consecutive-k< F Systems
    (Ieee-inst Electrical Electronics Engineers inc, 2013) Eryilmaz, Serkan
    We study the joint reliability importance (JRI) of two components in Lin/m/Con/k/n : F systems. A Lin/m/Con/k/n : F system consists of n linearly ordered binary components, and the system fails iff there are at least m nonoverlapping runs of k consecutive failed components (n >= mk). In particular, we obtain expressions for the JRI in Lin/m/Con/k/n : F systems when the components are s-independent & identical, when the components are s-independent & nonidentical, and when the components are exchangeable & s-dependent. We present extensive numerical illustrations.
