The approaches to the evaluation of the efficiency of the functioning of heterogeneous video information systems are considered. It is shown that the hierarchy model as a quantitative description of the structural and functional organization can serve as a means of analyzing information flows and system efficiency in terms of graph theory. The criterion of dominance for the evaluation of the efficiency of heterogeneous video information systems is analytically presented. It is shown that in the loaded graph of a heterogeneous system the weights of individual nodes represent the efficiency of this node, and with its increase the degree of influence (dominance) of this node on the remaining nodes of the system and on the system as a whole grows, and conversely, with a decrease in the weight of the node it rises its dependence on other nodes. The influence of the length of interstitial paths on the efficiency of the system is taken into account, taking into account the partial loss of information during its propagation through the graph. Numerical calculations of the efficiency of systems based on the dominance criterion are given, the results of which confirm the indicated theoretical positions.
