Exact Reliability for a Multi-State Consecutive Linear (Circular) k-out-of-r-from-n:F System
Abstract
The multi-state consecutive linear (circular) k-out-of-r-from-n:F system consists of n linear (circular) ordered multi-state components. Both the system and its components can have m different states: from complete failure (zero state) up to perfect functioning ((m−1) state). In this paper we suggest, for the first time, exact reliability for these models. The system is at state below j if and only if at least kj components out of any r consecutive are in state below j(k1≤k2≤⋯≤km−1). Recent efforts in these branches have focused on simple situations or approximation bands for their reliability in two-state or multi-state models but closed form and exact amount not gained. In the continuation, there are the matlab programs of linear (circular) reliability system and j state probability for kj in system. In the following, we applied comparative and numerical results and calculated the exact reliability of this strategic systems. Finally, we calculated the exact reliability for two real-world practical examples.
