The intensification of negative processes of natural and man-made nature, the growing number of cyberattacks, and terrorist threats have raised the issue of protection of critical infrastructure (CI), which is vital for the security of man, society and the state as a whole. Disruption of these facilities can lead to deterioration of: economic security, life and health of the population, domestic and state security, defense capabilities of the state, environmental security. Given the importance of this issue, a simplicial analysis of the structure of the cognitive model was conducted to study the level of protection of the object of CI. To achieve this goal, the dimension of simplexes is determined, a simplicial complex is constructed, which is a sequence of simplexes, which are arranged in descending order of their dimension, and its first structural vector is found, which allows to establish connectivity of complexes at all levels. Note that for each dimension value the number of different equivalence classes is set. Based on the obtained data, a set of control concepts for the whole system is formed and the connected components of the fuzzy cognitive model are established. The study of the relationships within each block of concepts of this simplicial complex will increase the level of security of the object of CI. And the obtained results are useful for making managerial decisions related to strengthening the safe operation of the CI facility, rapid adaptation to constantly changing conditions, resisting the impact of threats of any kind.
