The Analytic Hierarchy Process (AHP) is a structured decision-making tool that helps individuals and groups prioritize options based on multiple criteria. It breaks down complex problems into smaller, more manageable parts, allowing users to compare different elements systematically. AHP involves creating a hierarchy of criteria and alternatives, where each element is evaluated based on its importance. Users assign numerical values to express their preferences, which are then used to calculate a weighted score for each option, facilitating informed decision-making.
