This paper presents an interactive approach for solving multi-level multi-objective quadratic fractional programming problems with fuzzy parameters in the constraints. Firstly, the concept of α-cut is applied to transform the fuzzy mathematical problem into a common deterministic one. Then, the quadratic fractional objective functions in each level are transformed into non-linear objective functions based on a proposed transformation. Secondly, the interactive approach was extended to solve such problem. Finally, an illustrative numerical example is introduced to demonstrate the applicability and performance of the proposed approach.
