Fuzzy linear programming (FLP), as an application of fuzzy set theory in linear
decision making problems, has been allocated to itself a wide variety of research in operation
research field. In this study, the existing algorithms for solving a special type of linear
programming problems with fuzzy parameters are reviewed. The FLP problem here involves
the symmetric trapezoidal fuzzy numbers for decision variables, the coefficients of decision
making in the objective function and the right-hand-side of the constraints. It is assumed all
of decision variables are restricted to lie within fuzzy lower and fuzzy upper bounds. A
solution approach is proposed to obtain the fuzzy optimal solution of the same problem based
on duality results
