For Problem 19, develop your own pairwise comparisons for the criteria you might use to select an apartment complex or other dwelling in your college community, and develop your own AHP ranking for the possible apartment complexes you might live in.

Data From Problem 19

Katnis Evergreen, a junior at Tech, is moving out of the dorms where she has lived for 2 years into an apartment in town. She is considering three apartment complexes—the Terraces, the Vistas, and Foxfield. She is going to evaluate the apartments using three criteria—cost, condition (age, upkeep, etc.), and location (i.e., proximity to campus, transportation, shopping). Katnis’s pairwise comparisons for each of the three apartment complexes for each criterion and her pairwise comparison matrix for the three criteria are as follows:

a. Determine an overall ranking of the three apartment complexes by using AHP.
b. Check the pairwise comparisons for the criteria for consistency, and indicate whether the level of consistency is acceptable.
