Validation of the method in practical testing shows surprisingly good agreement with actual measured values. assigning points) or the free assignment of priorities. The core of AHP is the comparison of pairs instead of sorting (ranking), voting (e.g. Sometimes alternatives are already implicitly defined by the problem and it is sufficient merely to define the priorities. Evaluate alternatives according to the priorities identified – what alternative optimum solution is there to the decision problem?.Calculate the priorities and a consistency index – were my comparisons logical and consistent?.blue or green? Which do I prefer, and by how much do I prefer one or the other color? Pair comparison of criteria in each category – e.g.Structure the decision problem in a hierarchy – what are the categories and criteria that figure into my decision?.Define the goal of the decision – what do I want to decide, for what purpose, and what are my alternatives?.The basic steps in the solution of a decision problem using AHP are quite simple: Mathematically, the method is based on the solution of an “eigenvalue problem” – but this is mentioned here only tangentially and is not meant to dissuade anyone. In AHP, values like price, weight, or area, or even subjective opinions such as feelings, preferences, or satisfaction, can be translated into measurable numeric relations. AHP stands for analytic hierarchy process, and belongs to the multi-criteria decision making methods (MCDM) group. Called AHP, it is now used around the world in many different fields. Saaty, in which he describes his method for the mathematical treatment of decision problems, which he developed in the 70s. Or “Mathematical Principles of Decision Making” is the title of a book by Prof. Read my simple write-up about AHP for people, who have not heared about the method. AHP stands for analytic hierarchy process, and belongs to the multi-criteria decision making methods (MCDM).
