A fuzzy dual simplex method for fuzzy number linear programming problem

Fuzzy number linear programming (FNLP) problems have recently attracted some interests. In this paper, we give a fuzzy dual algorithm for solving linear programming problems with fuzzy numbers by using the duality results which are proposed by Mahdavi-Amiri et al. in [4]. This algorithm is useful for sensitivity (or post optimality) analysis using the fuzzy primal simplex tableaus.
