This paper at www.excelsoftware.com/system_models.pdf shows how a
dynamic system is modeled as a Causal Loop Diagram where nodes
represent system variables and connecting lines represent causal
effects. The changing value of one variable can cause another to
increase or decrease as described by equations. A time simulation of
the model yields results presented with live charts, graphs and tables.
This paper is illustrated with example models, time simulations and
graphs from the WinA&D modeling tool for population growth, bank
balance, demographics, production and water management.
