Mean residual lifetime assessment approach for a multi-state standby system

In this paper, a new MRL assessment approach for multi-state standby system is considered. The three-state backed up with binary cold unit. Given that the at specific state time t, obtaining worth considering in conducting maintenance and repair plans of system. For different degradation rates points, results are examined. An HCTMP considered degradation. Therefore, when observed to be its perfect state, decrease an increase all failure However, partial not affected by rate pertained state. has known failed before t unit increases whereas perfect(or partial) constant increases. Moreover, cost evaluation analyzed. supported numerical examples graphical representations.
