Intuitionistic fuzzy linear programming and duality: a level sets approach

Abstract

The paper is concerned with linear programming problems whose input data may be intuitionistic fuzzy (IF) while the values of variables are always real numbers. We propose rather general approach to this type of problems based on level sets, and present recent results for problems in which the notions of feasibility and optimality are based on the IF relations.

Special attention is devoted to the weak and strong duality.
