Abstract

In this paper, we consider the bilevel linear programming problem (BLPP) with the uncertainty, where all the coefficients in the problem are interval type-2 triangular fuzzy numbers (IT2TFN). First, we convert an interval type-2 triangular fuzzy bilevel linear programming problem (IT2TFBLPP) to an interval BLPP. In the next step, we solve BLPPs and obtain solution as an IT2TFN.
