... as the importance analysis of a system. Reliability analysis uses two main models: the binary-state system and the multistate system (MSS). To evaluate the reliability of MSS with binary-state components, computing methods of survival signature are studied. The structural functions of MSS and the survival signature...

... in contributing to system reliability. Then, when a component with high importance fails, it is swapped by another component with lower importance from the system which has not yet failed. The survival signature methodology is implemented to assess the reliability of PMS when there is a possibility of components...
