The Sensitivity Analysis of Bi-level Decision Problem Based on Modified Simplex Method

Abstract—The bi-level decision making system involves two optimization decision problems. The target value of the upper level decision problem is implicitly determined by the solution of the lower problem. In This paper discusses the sensitivity analysis of bi-level linear programming while the value coefficients of the lower level decision contains parameter and studies the conditions of optimal solution while parameter continue (or perturbation) in definite direction. The result provides the decision basis for decision maker.) Keywords- Bi-level decision, Sensitivity analysis, Parameter, Feasible set, Admissible s
