Abstract

Multicriteria decision-making methods have significant applications in land evaluation and planning. These methods assist decision-makers in assessing various options based on diverse criteria. One of the most comprehensive multicriteria decision-making models is the Analytic Hierarchy Process (AHP), introduced by Thomas L. Saaty in 1970 (Saaty, 1970). This method consists of four stages: creating a decision hierarchy tree, constructing a pairwise comparison matrix, calculating the weights of criteria, and estimating the consistency ratio. AHP enables a more thorough examination of impacts and priorities. Furthermore, this method facilitates participatory decision-making and adaptation to local conditions, ultimately leading to sustainable development.
