Parivertailumatriisi
Parivertailumatriisi, in English known as a pairwise comparison matrix, is a square matrix used in decision analysis to capture judgments about the relative importance or preference of a set of elements by comparing them two at a time. Each entry aij expresses how much more important or preferred item i is relative to item j. The matrix is typically reciprocal, meaning aji = 1 / aij, and the diagonal elements are 1 because an item is equally important as itself.
Commonly the entries are drawn from Saaty’s 1–9 scale, where 1 denotes equal importance and higher numbers
From a parivertailumatriisi, a priority vector or weights are derived to express the relative importance of
Consistency is a key consideration, since human judgments can be inconsistent. Measures such as the Consistency
Applications and context: parivertailumatriisi is a central component of the Analytic Hierarchy Process (AHP) and other
