the study of the impact that changes in one or more parts of the model have on other parts of the model
What is goal-seeking analysis?
finds the inputs necessary to achieve a goal such as a desired level of output
What is optimization analysis?
an extension of goal-seeking analysis, finds the optimum value for a target variable by repeatedly changing other variables, subject to specified constraints
