The Analytic Hierarchy Process (AHP) developed by Saaty (1977, 1980) is a robust and flexible multi-criteria decision analysis technique based on the prior articulation of preferences by the decision maker. It allows to analyze multi-criteria decision problems with both qualitative and quantitative aspects.
The AHP can be summarized as a four-step procedure:
