The main aim of this paper is to deal with a fuzzy version of Farkas lemma involving
trapezoidal fuzzy numbers. In turns to that the fuzzy linear programming and duality theory on these
problems can be used to provide a constructive proof for Farkas lemma.
Keywords Farkas Lemma, Fuzzy Linear Programming, Duality, Ranking Functions.
