MULTIPLE CHOICE 1. A decision with more than one objective a. cannot have an optimal solution. b. requires the decision maker to place the objectives in some order of importance. c. depends on the probability of satisfying each objective. d. should be decomposed into a separate model for each objective. ANS: B PTS: 1 TOP: Introduction 2. Variables that indicate the distance a target is from the level achieved are called a. goal variables. b. target variables. c. deviation variables. d. preemptive variables. ANS: C PTS: 1 TOP: GP: deviation variables 3. Preemptive priorities in goal programming a. show the target values for the problem. b. prevent sacrifice of a goal to satisfy a lower level one. c. force the problem to be a standard linear program. d. limit deviations to d only. ANS: B PTS: 1 TOP: GP: preemptive priorities 4. Deviation variables that occur in the objective function indicate a. the targets. b. the priorities. c. only the areas that are of concern. d. the difference between all actual and target values. ANS: C PTS: 1 TOP: GP: objective function 5. The variable d- measures a. the amount over the target and is similar to a slack. b. the amount under the target and is similar to a slack. c. the amount over the target and is similar to a surplus. d. the amount under the target and is similar to a surplus. ANS: B PTS: 1 TOP: GP: deviation variables 6. The constraint 5x1 + 3x2 150 is modified to become a goal equation, and priority one is to avoid overutilization. Which of the following is appropriate? a. Min P1d1 ; 5x1 + 3x2 + d1 d1+ = 150 b. Min P1d1+ ; 5x1 + 3x2 + d1

d1+ = 150 c. Min P1d1+ ; 5x1 + 3x2 + d1+ = 150 d. Min P1d1+ ; 5x1 + 3x2 d1+ = 150 ANS: B PTS: 1
