The fuzzification comprises the process of transforming crisp values into
grades of membership for linguistic terms
of fuzzy sets. The membership function is used to associate a grade to each linguistic
term.
Example 16.1.1
For the fuzzification of the car speed value
the
two membership functions
and
from Figure
16.2 can be used, which characterise a low
and a medium speed fuzzy set, respectively.
The given speed value of
belongs with a grade of
to the fuzzy set ``low'' and with a grade of
to the fuzzy set ``medium''.
