A method for solving linear programming problems with triangular fuzzy coefficients using new fuzzy ranking

Abstract

In this paper a new approach for ranking fuzzy numbers based on defuzzification is introduced. A new method for defuzzification triangular fuzzy numbers and trapezoidal fuzzy numbers based on right and left sprits of fuzzy numbers is developed first and then it is used to formulate defuzzification for fuzzy numbers. The approach is illustrated by numerical examples.
