Question 3

A required step in the analytic hierarchy process is to determine

Accepted Answer

Determining the relative importance of the criteria is a key step in the analytic hierarchy process, as it allows decision makers to prioritize and weigh the different factors that will impact their decision. Without this step, it would not be possible to effectively use the AHP to make informed decisions. A, B, and D are not correct choices, as they do not accurately describe a critical step in the AHP process.

Question 5

When using a linear programming approach to solving a goal programming problem,a linear program must be solved for each

Accepted Answer

A linear programming approach to solving a goal programming problem involves solving a linear program for each priority level, not for each goal, pair of deviation variables, or pairwise comparison. This is because goal programming organizes goals into a hierarchy of priorities, and the linear program is adjusted to optimize the goals according to their assigned priority levels.

Question 6

Computing the consistency ratio for a criterion's pairwise comparison matrix is the next step after

Accepted Answer

The consistency ratio is calculated after developing the criterion's priority vector, which is derived from the pairwise comparison matrix. This step ensures that the judgments made in the pairwise comparison are consistent.

Question 7

Deviation variables that occur in the objective function

Accepted Answer

Deviation variables allow for a range of acceptable values rather than just one specific target value. This allows for the possibility of not meeting the target exactly and provides more flexibility in the optimization process. The other options are not accurate explanations of deviation variables.

Question 8

Pairwise comparisons are used to

Accepted Answer

Pairwise comparisons involve comparing both criteria and choices. By comparing criteria in terms of the overall goal, the decision maker can determine the relative importance of each criterion. By comparing choices on each criterion, the decision maker can determine which choice is the best for each criterion. Therefore, option C is the best choice as it includes both aspects of pairwise comparisons.

Question 12

The steps of the scoring model include all of the following EXCEPT

Accepted Answer

Pairwise comparison matrix is not a step in the scoring model; it is more commonly associated with methods like the Analytic Hierarchy Process (AHP) for making decisions. The scoring model involves listing criteria, weighting them, rating alternatives against these criteria, and computing total scores.

Question 14

Inconsistency in pairwise judgments is indicated by a consistency ratio that is

Accepted Answer

The consistency ratio measures the degree of inconsistency in pairwise judgments. If the consistency ratio is less than 0, it means there is no inconsistency. If the consistency ratio is greater than 0.10, it indicates some inconsistency but it may still be acceptable depending on the context. However, if the consistency ratio is greater than 0.50, it indicates significant inconsistency and the judgments need to be revised or re-evaluated. If the consistency ratio is greater than 1.00, it means that the judgments are entirely inconsistent and cannot be relied upon. Therefore, the best choice is B, which identifies a threshold for acceptable inconsistency.

Question 15

Goal programming with preemptive priorities never permits trade-offs between

Accepted Answer

In goal programming with preemptive priorities, goals with different priority levels are assigned different levels of importance, and there can be no trade-offs between goals of different priority levels. Within each priority level, however, trade-offs may be permitted, even if the goals have the same weights. Therefore, option B is the correct choice. Option A and C are not correct because trade-offs may be permitted within a priority level. Option D is also incorrect since the purpose of goal programming is to find an optimal solution that balances different goals.

Question 17

The goal programming problem with the objective function Min P₁(d₁⁺)+ P₂(d₂−)is initially solved by the computer and the objective function value is 0.Which of the following constraints should be added for the second problem?

Accepted Answer

Since the objective function value is 0, it means that the deviations from the target values (represented by the d variables in the objective function) are minimized to 0. Therefore, adding a constraint that directly sets the expression involving these deviations to 0 (as in option A) ensures that the solution found in the first problem is maintained, which is consistent with the goal of having no deviations from the target values.

Question 18

Question 19

The variable d− measures the amount

Accepted Answer

The variable d- measures the amount by which the actual value of a decision variable falls short of its target value. Therefore, it is less than the target and is similar to a slack. Choice B is the best option as it correctly identifies d- as being less than the target, which is true.

Question 20

The overall priorities for decision alternatives

Accepted Answer

The overall priorities for decision alternatives indeed involve the sum of the products of the criterion priority times the priority of the decision alternative with respect to that criterion, sum to 1 to ensure a normalized comparison, and indicate a preference without mandating a specific choice, making all the provided options correct.
