We summarize the requirementsRequirement for sustainable development, basic resourcesBasic resource, finiteness of human knowledgeKnowledge, and the needsNeeds leading to systemSystem requirementsRequirement. We present a general hierarchyHierarchy of systemsSystem, including natural and technical systemsSystem. SelfSelf-organizing system-organizing systemsSystem are the highest in the hierarchy of technical systemsHierarchy of technical systems, thus providing, in special cases, all other systemsSystem lower in the hierarchyHierarchy. We do not have a single system theorySystem theories, but many theoriesTheory complement each other. A modern form of general theory of systemsGeneral theory of systems (general system theory) is the complexity theoryComplexity theory, a spin-off of cyberneticsCybernetics and artificial intelligenceArtificial intelligence and related to system dynamicsSystem dynamics. The system archetypesSystem archetypes include, for example, feedbackFeedback, optimizationOptimization and decision-makingDecision-making, hierarchyHierarchy, and degree of centralizationDegree of centralization. The most advanced systemsSystem are nonlinear and dynamic such as nonequilibrium systemsSystem representing different whirlpools in nature.
