Books, Courses and Tutorials

  • Business Dynamics by John Sterman is the definitive system dynamics text, and includes many Vensim models.
  • Erik Pruyt at the Delft University of Technology has written an electronic case book titled “Small System Dynamics Models for BIG Issues”. It can be downloaded for free at
  • Hartmut Bossel’s System Zoo series is an excellent introduction to modeling, particularly in the natural sciences, and includes model listings in Vensim notation. The models are linked here.
  • Modeling the Environment by Andy Ford is a good introduction to models of the natural world and the interface with policy; most models are reproducible or provided in Vensim.
  • Juan Martin Garcia has published the book Theory and Practical Exercises of System Dynamics that introduces system dynamics and provides a number of detailed examples with in Vensim for the construction of models. The book is also available in Spanish.
  • Craig W. Kirkwood at Arizona State University maintains a System Dynamics Resource page with a short tutorial for Vensim PLE.
  • Pegasus Communications carries most of the classic system dynamics books as well as other media.  These books may not be up on their web site yet — check with them directly.
  • An older but still useful text is Introduction to System Dynamics Modeling with DYNAMO,  by G.P. Richardson and A.L. Pugh (The MIT Press, Cambridge, MA, 1981).
  • System Dynamics resulted from the pioneering efforts of Jay W. Forrester to apply the engineering principles of feedback and control to social systems. One of the earliest, and still one of the best references in this field is Industrial Dynamics by Jay W. Forrester (The MIT Press,30 Cambridge, MA, 1961).
  • A simpler introduction to System Dynamics along with a number of exercises is Principles of Systems by Jay W. Forrester (The MIT Press, Cambridge, MA, 1968).
  • Another useful resource, containing a number of interesting real world examples is System Enquiry, A System Dynamic Approach by Eric F. Wolstenholme (John Wiley & Sons, New York 1990). This book also gives a brief introduction to what, in this manual, is called policy optimization.
  • A very popular and readable book covering many conceptual issues in thinking and acting systemically on problems is The Fifth Discipline by Peter M. Senge (Doubleday, New York, 1990).
  • An interesting and controversial work, World Dynamics by Jay W. Forrester (The MIT Press, Cambridge, MA, 1971; second edition, 1973) discusses growth in a finite world. This model is supplied with Vensim.
  • Donella Meadows’ Thinking in Systems is a very accessible introduction to systems concepts.
  • MIT Open Courseware contains several system dynamics classes – look for 15.871 to 15.879.
