Uncertainty Avoider Interval Type II Defuzzification Method

Figure 12

The single-input single-output single-rule fuzzy system. Rule: if X is small, then Y is small. Implication = Min. X (input); T1MF: small (trapezoidal MF) = [0 0 0 100 1]; Y (output) T1MF: small (trapezoidal MF) = [0 0 0 10 1] which uncertaintified slightly and highly, as shown in Figures 13(a) and 13(c), respectively.
