passwort sicherheit has also been transversal when its principles, methods and proposals have influenced and generated the emergence and autonomous development of other scientific and practical activities such as theories of systems, information, regulation and control, and games; operations research, robotics, artificial intelligence, computer programming, information systems analysis, or econometrics. More recently, the theories of chaos and complexity occupy their space in the management of complex systems. Also the influence of cybernetics is perceived in other sciences that already existed when the one in question arose, such as administration and economics, and jurisprudence. In none of these definitions, nor in the arguments of these scientists and others equally prominent, can one appreciate the requirement, to the cybernetic system that is designed or analyzed, of a certain level of centralization in its subsystems. This science becomes truly useful when analyzing or designing a complex or very complex system, such as a large company spread across regions or nations, or a country. It is also very useful with probabilistic systems, with many different problems to solve in their subsystems and with little structuring in their parameters and variables.
