Type II Parametric Trapezoidal Approximation of Type II Generalized Bell-Shaped Fuzzy Number

The fact that fuzzy numbers allows other levels of membership except from 0 and 1 lead to the use of fuzzy numbers in various applications in cases where there is uncertainty. In type 1 fuzzy numbers, a crisp membership level is assigned to each x value. However, there may be cases where it is difficult to assign only one membership value to the membership level of each x value. In such cases, Type II fuzzy numbers can be used, which allow a fuzzy number membership value to be assigned to each x value. When using complex type fuzzy numbers in fuzzy number operations, sometimes there may be difficulties and it may be desirable to work with fuzzy numbers in a simpler structure. In this study, Type II generalized bell-shaped, Type II parametrical trapezoidal fuzzy numbers in simpler form are considered, and Type II parametrical trapezoid approximation of Type II generalized bell-shaped fuzzy number of is formed
