Asymmetric Triangular Membership Function for Fuzzy numbers and Application in Regression


The present study described the form of fuzzy number represented by function in terms of membership function, namely Symmetric Triangular Membership Function and Asymmetric and how to use this function in the regression and application by a numerical example and comparison between symmetry and asymmetry .Two methods were used (Ishibuchi and Nii, 2001) and (Yen et al., 1999) thus fuzzy coefficients , the least total of coefficients spreads which is represented by objective function and the linear model could be obtained.
