The basic principles of the formation of system hierarchies and complex systems with a hierarchical network structure are analyzed. The flow adjacency matrix for a complex hierarchical network system is determined, which allows us to investigate the functional features of the system, linking them with the components of the structure. The notion of the flow core is introduced, which allows us to construct simplified models of a system of a smaller dimension with simultaneous monitoring of the quantitative measure of maintaining their adequacy. The principles of formation of information and evaluation models of complex hierarchical network systems with consideration of the priority of their components and the level of fullness of data are proposed. The main advantage of the evaluation models is the smaller amounts of information that are much easier to analyze and allow us to timely locate the most threatening components of the system. For the study of heterogeneous inter-system interactions, the notions of association, conglomerate and system environment are introduced, which allow us to analyze the nature and effects of inter-system influences of different types.
