List of system theories as enumerated by Ludwig von Bertalanffy in “General System Theory” (1968):
- Classical system theory, basically maths.
- Computerization and simulation using models.
- Compartment theory: “the system consists in subunits with certain boundary conditions between which transport process takes place”.
- Set theory, which studies general formal properties of systems.
- Graph theory concerned with topological space.
- Net theory, a generalisation of sequences (http://en.allexperts.com/e/n/ne/net_(mathematics).htm).
- Cybernetics: “A theory of control systems based on communication (transfer of information) between system and environment and within the system, and control (feedback) of the system’s function in regard to environment.”
- Information theory “is based on the concept of information, defined by an expression isomorphic to negative entropy of thermodynamics”.
- Theory of automata (i.e. abstract machine – Turing machine 1936).
- Game theory which studies systems animated by rational players.
- Decision theory: maths about choices over alternatives.
- Queuing theory: optimization of arrangements under conditions of crowding.
