Sensitivity Analysis Sensitivity analysis allows researcher to determine how "sensitive" the optimal solution is to changes in data values. Hence the solution of a practical problem is not complete with the mere determination of the optimal solution Each variation in the values of the data coefficients changes the LP problem which may in turn affect the optimal solution found earlier Sensitivity analysis helps to study how the optimal solution will change with changes The purpose of sensitivity analysis is to determine changes in the optimal solution of the fuzzy number linear programming problem resulting from changes in the data. A linear programming problem with "n" decision variables and "m" constraints can be mathematically modeled . Thus, at this, point in our presentation of linear programming, we focus exclusively, on computer solution. 0000006331 00000 n stream 0000002184 00000 n Optimal Solution Optimal Objective Function Value. /Subtype /Form Chapter 5 - exercises to improve knowledge. %PDF-1.3 % This preview shows page 1 - 6 out of 30 pages.
