In this research paper, we will solve problems of Bi-level linear fractional programming (BL-LFP) by proposing an interactive approach. Based on the imposition of the relationship DM. to obtained adequate solution, DMs will updating the minimal adequate level at upper level permanently, and that is through. Firstly, the decision makers uncertainty is described by introducing the membership function and non-membership function. Secondly, the opting of minimum adequate degree, leads to obtain the adequate solution, with the overall adequate balance considerations among two levels. For more, this paper gives an algorithm of the proposed approach. At the end, we give a numerical example to explain the feasibility of that approach.

在这篇研究论文中，我们将通过提出一种交互式方法来解决双层线性分数规划（BL-LFP）的问题。基于强加关系DM。为了获得适当的解决方案，DM将永久地在较高级别上更新最小适当级别，即通过。首先，通过引入隶属度函数和非隶属度函数来描述决策者的不确定性。其次，选择最低程度的适当程度会导致获得适当的解决方案，并在两个层次之间总体考虑适当的平衡。对于更多内容，本文给出了所提出方法的算法。最后，我们给出一个数值示例来说明该方法的可行性。
