Abstract: 36 years ago, Thomas Saaty introduced a new mathematical methodology, called Analytic Hierarchy Process (AHP), regarding the decision-making processes. The methodology was widely applied by Saaty and by other authors in the different human activity areas, like planning, business, education, healthcare, etc. but, in general, in the area of management. In this paper, we provide two new proofs for well-known statement that the maximal eigenvalue is equal to for the eigenvector problem , where is, so-called, the consistent matrix of pairwise comparisons of type ( 2) with the solution vector that represents the probability components of disjoint events. Moreover, we suggest an algorithm for the determination of the eigenvalue problem solution as well as the corresponding flowchart. The algorithm for arbitrary consistent matrix can be simply programmed and used.
