A cost-based importance measure for system components: An extension of the Birnbaum importance

Abstract: In reliability engineering, component importance measures are used to prioritise components in a system for purposes such as reliability improvement and maintenance planning. Existing importance measures have paid little attention to the costs incurred by maintaining a system and its components within a given time period. Cost-effectiveness analysis, however, is critically important in increasingly competitive markets. This paper proposes a new cost-based importance measure which considers costs incurred by ma… Show more

“…Fangxing and Brown [21] proposed a new approach to prioritize distribution maintenance activities based on system reliability and cost-effectiveness. Shaomin et al [22] proposed a new cost based importance measure which considers costs incurred by maintaining a system and its components within a finite time horizon. Shubin et al [23] used the integrated importance measure to estimate the effect of a component residing at certain states on the performance of the entire multi-state systems.…”

“…CBCI is introduced as the extension of Birnbaum importance [25]. In our paper CBCI of component i is defined as: where ∂C i (t) and ∂R i represent the increase of system cost and system reliability caused by reliability improvement of i-th component, respectively.…”

Wu and Coolen [24] extended the Birnbaum importance to a cost-based importance measure. Borgonovo et al [2,3] proposed differential importance measure, and time-independent reliability importance for the risk evaluation.…”
