The (n,f,k) (<n,f,k>) system consists of n components ordered in a line or a circle and the system fails if and only if there exist at least f failed components or (and) at least k consecutive failed components. This type of models involves two common failure criteria of a system. In this paper, the...</n,f,k>

In recent decades, the Dunhuang oasis in the arid Northwest China has been undergoing significant changes due to social-economic development and expanded irrigation for agricultural production. Groundwater table was found to have significantly declined during the period of 1987–2007 owing to...

This paper is concerned with opportunistic maintenance on a multi-component cumulative damage shock model with stochastically dependent components. A component fails when its cumulative damage exceeds a given threshold, and any such a failure creates a maintenance opportunity, and triggers a...

The (n,f,k) system consists of n components ordered in a line or a cycle, while the system fails if, and only if, there exist at least f failed components or at least k consecutive failed components. For the linear (n,f,k) system with equal component reliabilities, the system reliability formula...
