A faculty committee in the department of management science at Tech is evaluating three new textbooks for its introductory management science course, which all business students are required to take. The texts, identified by the authors, are Adams/Jones, Barnes, and Cook/Smith.

The committee’s selection criteria are topical coverage, readability, cost, and the available supplements.

Following are the committee’s pairwise comparisons of the three textbooks for each of the four criteria and the committee’s pairwise comparisons for the criteria:

Coverage Textbook A B C A 1 1/5 1/4 B 5 1 3 C 4 1/3 1 Readability Textbook A B C A 1 2 3 B 1/2 1 3 C 1/3 1/3 1 Cost Textbook A B C A 1 1/2 1/5 B 2 1 1/3 C 5 3 1 Supplements Textbook A B C A 1 4 7 B 1/4 1 3 C 1/7 1/3 1 Criterion Coverage Readability Cost Supplements Coverage 1 1/2 1/4 2 Readability 2 1 1/3 5 Cost 4 3 1 3 Supplements 1/2 1/5 1/3 1 Using AHP, determine which textbook the committee should select. Check the consistency of the pairwise comparison matrix for the criteria. LO.1
