CORE DEFINITION

Decompose complex problems into hierarchical levels such as goals, criteria, and alternatives, and quantify weights through pairwise comparisons.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Mathematization of subjective judgment. When you face a multi-factor dilemma like "buying a house" (location, price, school district), AHP helps you turn the vague "roughly think" in your mind into precise "weight scoring" to calculate the optimal solution.

anchor

Anchor fast decisions

Based on the "pairwise comparison scale." Decompose multi-criteria decisions into a hierarchy, use a 1-9 scale to compare elements pairwise, derive weights from the eigenvector, and synthesize to rank alternatives.
