As a result of system modeling we built a global model of the integrated security system as an information system. The proposed model allows us to differentiate one model into a set of private models, the elements of which one by one form the stages of its operation. The model of structural functioning proposed in the work, based on the analysis of the schedule of different states gave the key to understanding the permissible-possible stages of reducing the time of decision-making and thereby optimize its energy efficiency.
