\(0\) | \(X < a\) | \(a\) has the lowest potential value of number of fuzzy number | |
\(\mu {\text{\ n }}_{\left( A \right)}^{\left( X \right)}\) | \(\frac{X - a}{{b - a}}\) | \(a \le X \le b\) | \(b\) has the higher potential value of number of fuzzy number |
\(\frac{c - X}{{c - b}}\) | \(b \le X \le c\) | \(c\) has the highest potential value of number of fuzzy number | |
\(0\) | \(X > c\) | \(c\) has the highest potential value of number of fuzzy number |
