The faulty measure of a circuit is defined fuzzily by three fuzzy sets namely

Robust $(R),$ Fault tolerant $($FT$)$ and Faulty $(F),$ defined by three membership

functions with number of faults occur as universe of discourses and is shown below.

Robust

rauIt tolerant

Faulty

Reliability is measured as $R^{**}=FFTR$ With a certain observation in

testing $(x,0\mathrm{.}3)inR,(x,0\mathrm{.}5)inFT,(x,0\mathrm{.}8)inF.$

Calculate the reliability measure in crisp value.

Calculate with $1)$ CoS $2)$ CoG $.$
