Bilevel Linear Programming with Fuzzy Parameters

Bilevel linear programming is a decision making problem with a two-level decentralized organization. The leader is in the upper level and the follower, in the lower. Making a decision at one level affects that at the other one. In this paper, bilevel linear programming with inexact parameters has been studied and a method proposed to solve a fuzzy bilevel linear programming using interval bilevel linear programming.
