Posted by Stefan Grösser <stefan.groesser@web.de> Dear members of the System Dynamics List-Server,
On behalf of the Student Chapter, I want to announce that we have recently issued our second newsletter which contains interesting topics about the current and future development of the Student Chapter. You find the newsletter on our website:
http://www.systemdynamics.org/chapters/ ... hapter.htm
We as the young researchers in the field of System Dynamics are, of course, interested in feedback about our activities. Prof. Jay Forrester did an important first step. Thank you very much. We have included his feedback in the newsletter.
Moreover, the Student Chapter has now its own listserve
http://www.systemdynamics.org/mailman/l ... udent-list
All of you are more than welcome to join the list-server and pose your feedback, questions, comments, etc.
Best personal regards,
Stefan Groesser

ANNOUNCE Student Chapter Newsletter
Posted by Bob Eberlein <bob@vensim.com> Hi Everyone,
That query was, I am afraid, somewhat confusing and the reposnses were even more confusing. I probably should not have posted the original query, and I have decided not to post the reponses.
At the abstract level of variables named S1 and S2 clearly pretty much anything is possible. Without a concrete problem statement there is not much that can be said on most topics.
As far as one varible being used multiple times in a flow equation - difinitevely yes. In Jay Forrester's world model investement depends both on ""population"" and ""capital investment multiplier"" which also depends on popupulation (through two more variables).
The best advice on this is to study as many models as possible, including the classics (everything written by Jay should work) and everything published in the topic area you are working. That gives you the bounds on what has been done. As far as what is possible - anything - you just need to be able to demonstrate that it makes sense.
