Abstract :
This paper addresses a type of fully fuzzy bilevel linear programming (FFBLP) wherein all the co-efficients and decision variables in both the objective functions and constraints are triangular fuzzy numbers. In order to obtain the fuzzy optimal solution, a new efficient method for FFBLP with unconstrained variables and parameters has been proposed, . This proposed approach is based on crisp bilevel programming. Some examples have been provided to illustrate these methods.
