<>The System Dynamics Group was founded in
the early 1960s by Professor Jay W. Forrester at MIT. At that time, he began
applying what he had learned about systems during his work in electrical engineering
to every day kinds of systems. What makes using system dynamics different
from other approaches to studying complex systems is the use of feedback loops.
Stocks and flows help describe how a system is connected by feedback loops
which create the nonlinearity found so frequently in modern day problems.
Computers software is used to simulate a system dynamics model of the situation
being studied. Running "what if" simulations to test certain policies
on such a model can greatly aid in understanding how the system changes over
time.

Systems Theory:
the transdisciplinary study of the abstract organization of phenomena,
independent of their substance, type, or spatial or temporal scale of
existence. It investigates both the principles common to all complex
entities, and the (usually mathematical) models which can be used to
describe them.

Systems theory or general systems theory or systemics is an interdisciplinary Interdisciplinarity article field which studies systems System article as a whole. Systems theory was founded by Ludwig von Bertalanffy Ludwig von Bertalanffy article , William Ross Ashby William Ross Ashby article and others between the 1940s 1940 article and the 1970s 1970 article on principles from physics Physics article , biology Biology article and engineering Engineering article and later grew into numerous fields including philosophy Philosophy article , sociology Sociology article , organizational theory Organizational theory article , management Management article , psychotherapy Psychotherapy article (within family systems therapy Family systems therapy article ) and economics Economics article among others. Cybernetics Cybernetics article is a related field, sometimes considered as a part of systems theory.
