Abstract
In this chapter, we will explain the fundamentals of the Analytic Hierarchy Process. The reader is referred to the original Saaty (2012)’s discussion of AHP or to Brunnelli (2015)’s for a theoretical introduction to the method. In this book, AHP concepts will be explained from a practical point of view, using examples for greater clarity.

Notes
- 1.
For this chapter, it is recommended that the reader follows the calculations of this example using a spreadsheet.
- 2.
Each criterion, alternative and the goal are collectively referred as model elements.
- 3.
In this figure, the intermediate values 2, 4, 6 and 8 are used to address situations of uncertainty. For example, when the decision maker is in doubt whether to rate a pairwise comparison as “moderately more important (3)” or “strongly more important (5)”, a possible solution is to rate it as “From moderately to strongly more important;” that is, a 4.
- 4.
Inconsistency will be explained later in our discussion.
- 5.
It is customary to refer to overall (also called general or final) priorities of the alternatives when they are calculated with respect to the whole model; that is, after the synthesis process.
