Fuzzy optimization of primal-dual pair using piecewise linear membership functionsKeywords: Linear primal-dual problems , Fuzzy environment , tolerance , Non-linear membership function Abstract: Present paper improves the model of Bector and Chandra [Fuzzy Sets and Systems, 125 (2002) 317-325] on duality in fuzzy linear programming by using non-linear membership functions. Numerical problem discussed by these authors has also been worked out through our non-linear model to demonstrate improved optimality of the results.
