The Eigenvector in lay language

Thomas Saaty
Journal: International Journal of the Analytic Hierarchy Process
Decision making depends on identifying a structure of criteria and alternatives of a decision. It also depends on experience and judgments to select the best alternative. In the Analytic Hierarchy Process (AHP) for decision making the criteria and alternatives are prioritized by forming matrices ...

Decision-making with the AHP: Why is the principal eigenvector necessary

Thomas Saaty
Journal: European journal of operational research
In this paper it is shown that the principal eigenvector is a necessary representation of the priorities derived from a positive reciprocal pairwise comparison judgment matrix A=(aij) when A is a small perturbation of a consistent matrix. When providing numerical judgments, an individual attempts...

Inconsistency and rank preservation

Thomas Saaty, Luis Vargas
Journal: Journal of Mathematical Psychology
Conditions for rank preservation in a positive reciprocal matrix that is inconsistent are provided. Three methods of deriving ratio estimates are examined: the eigenvalue, the logarithmic least squares, and the least squares methods. It is shown that only the principal eigenvector directly deals ...
