Figure 1-14. Relaionship between crisp value and Fuzzy membership value for the variable X
The crisp values ranges from 0 to x2 belong to the set Xsmall. The crisp
values ranges from x1 to x3 belong to the set Xmedium. The crisp value
ranges from x2 to x4 belongs to the set Xlarge.
The crisp value from x1 to x2 of the Xsmall set and Xmedium set with
different membership value as mentioned in the Figure 1-14. Corresponding
membership value decreases gradually from 1 to 0 in the Xsmall set. But the
corresponding membership value increases gradually from 0 to 1 in the
Xmedium set.
Similarly the relationship between the crisp value and Fuzzy member
ship value for the variable ‘Y’ and the variable ‘Z’ are mentioned in the
Figure 1-15 and Figure 1-16 respectively.
