Fuzzy system reliability analysis based on level(1−β,1−α) interval-valued fuzzy numbers and using statistical data

In this paper, we consider the fuzzy reliability of the serial system and the fuzzy reliability of the parallel system problems. We use the statistical data to derive a level 1−α fuzzy numbers and a level (1−β, 1−α) interval-valued fuzzy numbers. Then, we compute both fuzzy reliability of the serial system and fuzzy reliability of the parallel system based on level (1−β, 1−α) interval-valued fuzzy numbers.
