ST101: Introduction to Systems Dynamics: Stocks and Flows
Bob Hawkins
This Insight has been developed as an introduction to the basics of Systems Dynamics as part of a series of models to explore the dynamics of growth and decline in a simple environment.  It is the first Insight in a series of four and the next Insight can be found here.

The model is on one of the activities included in the Open University short course called Understanding the environment: Complexity and chaos. The course can be accessed here.
