Linear programming problems with trapezoidal
fuzzy numbers have recently attracted much
interest. Various methods have been develope
d for solving these types of problems. Here,
following the work of Ganesan and Veeramani and
using the recent approach of Mahdavi-Amiri
and Nasseri, we introduce the dual of the
linear programming problem with symmetric
trapezoidal fuzzy numbers and establish some duality results. The results will be useful for post
optimality analysis
