| Summary: | The lifetimes of components in unrepairable systems are considered as random fuzzy variables
since randomness and fuzziness are often merged with each other. Then we establish the fundamental
mathematical models of random fuzzy unrepairable systems, including series systems, parallel systems,
series-parallel systems, parallel-series systems, and cold standby systems with absolutely reliable conversion
switches. Furthermore, the expressions of reliability and mean time to failure (MTTF) are given for
the above five random fuzzy unrepairable systems, respectively. Finally, numerical examples are given to
show the application in a lighting lamp system and a hi-fi system. |
