Question
. All of the following are true concerning multicriteria decision making except:
A. multicriteria problems can have more than one goal or objective when making decision.
B. goal programming can be used to solve certain types of multicriteria problems.
C. all criteria will be met (i.e. all objectives will be satisfied ) when solving a multicriteria problem.
D. All of the above are true concerning multicriteria problems.
2. The objective function in a goal programming model seeks to minimize the deviation from goals in the order of goal priorities.
A. True
B. False
3. All of the following are characteristics of a goal programming problem or model except:
A. At least one or both deviational variances in a goal constraint must equal zero.
B. Goals, or objectives, of the model are added in order of importance.
C. A positive deviational variable is the amount by which a goal is exceeded while a negative deviational variable is the amount by which a goal is underachieved.
D. All goal constraints are inequalities.
4. The Analytic Hierarchy Process (AHP) is a method that can be used for ranking several decision alternatives with only one criterion (objective) each and selecting the best one.
A. True
B. False
5. All of the following are true concerning using scoring models for multicriteria decision making except:
A. the scores for each criteria are divided by the weights in order to determine whcih alternative is the best
B. the alternative with the highest weighted total score is the one that is chosen.
C. each criteria is assigned a weight according to its realtive importance to the decision.
D. each criteria is scored or graded according to how well the alternative satisfies the given criteria.
6. Goal programming is a form or variation of linear programming that allows for more than one objective or goal in the objective function.
A. True
B. False
7. All of the following are true concerning using pairwise comparisons with the Analytical Hierarchy Process (AHP) method except:
A. pairwise comparisons are used to create both the preference vector and preference matrix.
B. pairwise preferences that are approximately equally preferred have a lower score or value than pairwise preferences where one item is greatly preferred over another.
C. pairwise comparisons are completely objective in their preferences.
D. pairwise comparisons in one direction result in a reciprocal score in the opposite direction, i.e. if a comparison of A and B results in a score of 7 then the comparison of B to A result in a score of 1/7.
8. When combining the preference vector and preference matrix with AHP, the decision alternative with the highest score is the best decision to choose.
A. True
B. False
9. With AHP, perfect consistency will result in a Consistency index (Cl) of 1.0.
A. True
B. False
10. With scoring models, all of the following are true concerning the criteria weights except:
A. more important decision criteria are assigned weightss with larger values.
B. the cumulative scores that are calculated using the decision criteria weights and scores are simply weighted averages for each decision alternative.
C. the sum of the decision crieria weighs will always be greater than 1.
D. All of the above are true concerning the criteria weights used with scoring models.
