//| - Triangular membership function |
| |||
//| - Trapezoidal membership function |
| |||
//| - Constant membership function |
| |||
//| - Defuzzification method of center of gravity (COG) |
| |||
//| - Defuzzification method of bisector of area (BOA) |
| |||
//| - Defuzzification method of mean of maxima (MeOM) |
