(.): The paper investigates the functioning of resource networks with assigned arc priorities. This class of models, which are directed graphs with discrete dynamics of resource reallocation between vertices, extends the classical theory of resource networks through the introduction of an arc hierarchy. The main objective of the article is to analyze qualitative changes in the network dynamics induced by the introduction of priorities. A formal resource allocation rule is defined, according to which the flow from a vertex is formed in stages, starting from the arcs of the highest priority. It is shown that this rule allows for the combination, within a single model, of properties that are incompatible in the classical case. For instance, the possibility of coexistence of cycles of different periodicities depending on the total resource quantity. Theorems on the existence of threshold values for the total resource, which separate different operational regimes of the resource network, are proved. A recursive approach, based on decomposing the original network into a sequence of subnetworks according to priority levels and analyzing residual networks, is proposed. For the case of a regular residual network, a constructive method for computing the limit state is developed. A number of examples, demonstrating how the availability of priorities can lead to the loss of the regularity property and a significant increase in the complexity of the network's dynamic behavior, are provided.
