The Analytic Hierarchical Process (AHP) and the Analytic Network Process (ANP) are used to measure intangibles using human judgment.

AHP/ANP are the most powerful synthesis methodologies for combining judgment and data to effectively rank options and predict outcomes.

These are structured techniques for organizing and analyzing complex decisions, based on mathematics and psychology. They were developed by Thomas L. Saaty.

They have particular application in group decision making, and are used around the world in a wide variety of decision situations, in fields such as government, business, industry, healthcare, shipbuilding and education.

Rather than prescribing a "correct" decision, these methods help the decision makers to find a solution that best suits their goal and their understanding of the problem. It provides a comprehensive and rational framework for structuring a decision problem, for representing and quantifying its elements, for relating those elements to overall goals, and for evaluating alternative solutions.
