A new approach for sensitivity analysis for intuitionistic fuzzy linear programming problems

This paper focuses on sensitivity analysis of Intuitionistic Fuzzy Linear Programming (IFLP) problem. In this paper, a new approach is proposed for solving same type of problems. The main advantage of proposed method over the existing method is that if the same problems are solved by both the existing as well as proposed method then the obtained results will be same, while, it is easy and less time consuming to apply the proposed method as compared to existing method. Also, we study how changes in the coefficients of objective function, the coefficients matrix and the right-hand-side vector of constraints of the IFLP problems with the intuitionistic fuzzy order relation in the objective function and the constraints under linear accuracy function affect the intuitionistic fuzzy optimal solution. Finally, we obtain the optimal value function with intuitionistic fuzzy coefficients in each case and the results are described by numerical examples.
