The joint survival signature of coherent systems with shared components

Abstract The concept of joint bivariate signature, introduced by Navarro et al. [13], is a useful tool for quantifying the reliability two systems with shared components. As univariate system Samaniego [17], its applications are limited to only one type components, which restricts practical use. Coolen and Coolen-Maturi [2] survival generalizes Samaniego’s signature can be used multiple types This paper introduces components some between systems. A particularly important feature that functioning these considered at different times, enabling computation relevant conditional probabilities regard system’s on status another it shares Several opportunities application related challenges further development presented briefly discussed, setting out an direction future research.
