Transformation linear membership function by using the modified S- curve

الملخص EN

In this paper, we concentrate on two cases of fuzzy linear programming problems (FLPP) : LPP with coefficient of objective function and coefficient of available resources and constraint are trapezoidal and triangular of fuzzy numbers respectively.

Though by using a-cut, fuzzy numbers (fuzzy triangular and fuzzy trapezoidal ) can be transformed into interval numbers and by taking one type of non-linear membership function this meant logistic function, we propose here the "modified S-curve function by simplex method ".
