A consumer group is using AHP to compare four used car models.Part of the pairwise comparison matrix for "repair frequency" is shown below. a.Complete the matrix. b.Does it seem to be consistent? ​

Correct Answer

The matrix is not consistent.A to B is 5,B to C is 3,C to D is 4,yet D to A is 6.

The priority matrix shows the priority for each item on each criterion.

A problem involving only one priority level is not considered a goal programming problem.

AHP allows a decision maker to express personal preferences about the various aspects of a multicriteria problem.

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

John Harris is interested in purchasing a new Harley-Davidson motorcycle.He has narrowed his choice to one of three models: Sportster Classic,Heritage Softtail,and Electra Glide.After much consideration,John has determined his decision-making criteria,assigned a weight to each criterion,and rated how well each decision alternative satisfies each criterion. Using a scoring model,determine the recommended motorcycle model for John.

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?

A consistency ratio greater than 0.10 indicates inconsistency in the pairwise comparisons.

One limitation of a scoring model is that it uses arbitrary weights that do not necessarily reflect the preferences of the individual decision maker.

Objectives in multicriteria problems seldom conflict.

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

Rosie's Ribs is in need of an office management software package.After considerable research,Rosie has narrowed her choice to one of three packages: N-able,VersaSuite,and SoftTrack.She has determined her decision-making criteria,assigned a weight to each criterion,and rated how well each alternative satisfies each criterion. ​ Using a scoring model,determine the recommended software package for Rosie's.

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

An ATM is to be located in a campus union building so that it minimizes the distance from the food court,the gift shop,and the theater.They are located at coordinates (2,2),(0,6),and (8,0).Develop a goal programming model to locate the best place for the ATM.

Requiring a decision maker to provide judgments about the relative importance of each criterion and then specifying a preference for each decision alternative using each criterion is the purpose of the analytic hierarchy process.

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