•The mathematical models used in DSSs
•Sensitive analysis is the study of the impact that changes in one or more parts of a model have on other parts or the outcome.
•Usually, we check the impact that changes in input (independent variables) have on outcomes (dependent variables).
•For example, in the classic economic model:
•Dependent variable is quantity demanded, whereas
•Independent variables are price, advertising, disposable income, and competitor’s price
•So, the dependent variable change response to changes in the independent variable.
