The Analytic Network Process (ANP) is a useful tool in urban and regional planning because it considers the complex relationships between different decision levels and attributes. Unlike the Analytic Hierarchy Process (AHP), which assumes a strict hierarchy, ANP allows for interdependencies among criteria and sub-criteria. By modeling decision problems as networks rather than hierarchies, ANP can capture these interrelationships more effectively. The four main steps in implementing ANP involve constructing a model, making pair-wise comparisons, forming a supermatrix, and prioritizing alternatives. This method helps in selecting the best alternative based on priority weights or a desirability index.
