ABSTRACT

In previous studies, it is pointed out that in several situations it is better to use interval-valued fuzzy numbers instead of triangular or trapezoidal fuzzy numbers. But till now, there is no method that deals with the sensitivity analysis of such linear programming problems in which all the parameters are represented by interval-valued fuzzy numbers. In this paper, a new method is proposed for the sensitivity analysis. Finally, the proposed method is illustrated using a numerical example.

Keywords: Interval-valued fuzzy numbers, interval-valued fully fuzzy linear programming problems, sensitivity analysis, ranking function.
