What distinguishes goal programming from traditional linear programming? Goal programming only focuses on a single objective. Goal programming does not involve constraints. Goal programming is only applicable to integer programming problems. Goal programming allows multiple objectives and deviations from goals. Question 12 In goal programming, what are "deviation variables" used for? Representing the constraints in the optimization problem Quantifying the uncertainty in the objective functions Representing the decision variables in the model Representing the difference between target values and achieved values for each goal
