System Dynamics Society
System dynamics is a methodology for studying and managing
complex feedback systems, such as one finds in business and other social
systems. In fact it has been used to address practically every sort of
feedback system. While the word system has been applied to all sorts of
situations, feedback is the differentiating descriptor here. Feedback
refers to the situation of X affecting Y and Y in turn affecting X perhaps
through a chain of causes and effects. One cannot study the link between
X and Y and, independently, the link between Y and X and predict how the
system will behave. Only the study of the whole system as a feedback system
will lead to correct results.

LECTURE: The Internet, Epidemics, and Kevin Bacon: The Emerging Science of Networks
by
Tom Johnson
on Thu 17 Mar 2005 08:23 AM MST
Abstract: There are networks in almost every part of our lives. Some of them are familiar and obvious: the Internet, the power grid, the road network. Others are less obvious but just as important.... This lecture looks at some new discoveries regarding networks, how these discoveries were made, and what they tell us about the way the world works. more »

What is System Dynamics
by
Tom Johnson
on Wed 16 Mar 2005 09:47 PM MST
<>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.

What is Systems Theory?
by
Tom Johnson
on Wed 16 Mar 2005 09:42 PM MST
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.
