A New Approach for Solving Fully Fuzzy Bilevel Linear Programming Problems

摘要: This paper addresses a type of fully fuzzy bilevel linear programming (FFBLP) wherein all the coefficients and decision variables in both objective function constraints are triangular numbers. proposes new simple-structured, efficient method for FFBLP problems based on crisp that yields optimal solutions with unconstraint parameters. some examples have been provided to illustrate these methods.
