Comment on 'Duality theory in fuzzy linear programming problems with fuzzy coefficients'

摘要

This note provides a counterexample to illustrate the incorrectness of the proof of Proposition 3.3 that was presented by Wu (Fuzzy Optim Decis Mak 2:61-73, 2003). The original proof of Proposition 3.3 by Wu can only be correct when the extra assumption mu((y) over tildei) (0) = 1 is added. The correct proof of Proposition 3.3 is also presented in this note.
