Abstract

The study of complex systems requires the use of various methods, which should provide useful information to ensure effective management. Using Q-analysis makes it possible to delve into the structure of the system and understand the complex relationship between its components. In the course of the study, concepts such as a structural tree, local maps, and the inheritance hierarchy were introduced, which make it possible to better understand the meaning of the system metrics obtained by Q-analysis. Then, on this basis, algorithms were developed to determine the basic metrics. They were applied to the banking system of Ukraine as of 2016. An interpretation of the results is proposed and their practical significance is described.
