SENSITIVITY ANALYSIS IN FUZZY LINERAR PROGRAMMING PROBLEMS

In this paper, some existing methods to deal with the sensitivity analysis of fuzzy linear programming problems are reviewed. Moreover, the shortcomings of some existing methods are pointed out and to overcome these shortcomings, a new method is proposed to discuss the sensitivity analysis of that kind of FLP problems in which the elements of coefficient matrix of the constraints are represented by real numbers and rest of the parameters are represented by symmetric trapezoidal fuzzy numbers. The advantages of the proposed method over existing methods are discussed.
