WebSensitivity measures how robust the optimal solution is. It applies to changes in the coefficients of the objective function value or to changes in the right-hand side values of the constraints. These changes can be either on one parameter only or simultaneously on more than one parameter. Web14 Mar 2024 · Sensitivity Analysis is a tool used in financial modeling to analyze how the different values of a set of independent variables affect a specific dependent variable under certain specific conditions. In general, sensitivity analysis is used in a wide range of fields, ranging from biology and geography to economics and engineering.
