This document provides an overview of the Analytic Network Process (ANP), which generalizes the Analytic Hierarchy Process (AHP) to problems that involve feedback and interdependence. The ANP uses a network structure rather than hierarchical levels and derives priority scales from matrices representing the influences between different elements. It involves constructing a supermatrix for each control criterion, weighting the supermatrices, and synthesizing the results. The ANP allows for inner and outer dependence between clusters of elements and can represent complex decision problems with feedback loops.
