Challenges to national defence in contemporary geopolitical situation

The paper deals with the theoretical problems of nonlinear dynamical systems with internal parameters, which can be called chaotic systems with some simplification. The science of chaos has a relatively short history and is not yet sufficiently reflected by experts in various fields, resp. The authors are confused with the terms confusion, coincidence, etc. The authors believe that in examining chaos, it is necessary to consistently distinguish systems, namely deterministic, stochastic, and chaotic. Specifically, possible and anticipated practical applications of chaos theory with a focus on the issue of congestion of traffic flows in road transport.
