ANP is a more general form of AHP of MCE. The ANP model is represented by a network structure indicating all dependences among clusters and determining the direction of influences. Figure 1 shows the ANP model for sustainable tourism planning. As can be seen in the figure, connections can be set among elements within a cluster (i.e., inner dependence); that is why there is a self-loop on that cluster. Connection can also be set between elements in different clusters (i.e., outer dependence); that is why a line or link appears between the clusters with an arrow on it from the cluster containing the parent node. The ANP process is described as follows
