Fuzzification
Measurement devices in technical systems provide crisp measurements,
like 110.5 Volt or 31,5 °C. At first, these crisp values must be
transformed into linguistic terms (fuzzy sets) . This is called
fuzzification.
The membership functions of the linguistic variable speed will be
determined below.
m_{very low}(40
km/h) 
= 
0 
m_{low}(40
km/h) 
= 
0.67 
m_{medium}(40
km/h) 
= 
0.33 
m_{high}(40
km/h) 
= 
0 
m_{very high}(40
km/h) 
= 
0 

By fuzzification
the crisp input values are transformed into fuzzy sets.
