【Abstract】 The quadratic-linear bi-level programming model with interval coefficients for upper objective function is studied. Firstly,the definition of the optimal value interval of quadratic-linear bi-level programming with interval coefficients is proposed. Secondly,the quadratic-linear bi-level programming model with interval coefficients is converted into two deterministic models. Then mixed integer programming method is used to solve the best optimal value and worst optimal value. Finally,numerical examples are given to demonstrate the effectiveness of the proposed method.更多还原
