Software for System Dynamics

Reference: QUERY Current software in S.D. to study the biological populations.

Hello Kedwards, hello colleagues:

This is Antonio Barron, SDQs novice user, learning of everybody, and trying to
contribute to the knowledge of the novicer, trhough my own experience in the
use of this techniques & tools of SD.
I am user of Dynamo & Vensim for windows (both), and a searcher of others
like Power-Sim, I-think,...
I recommend the first (dynamo) as a classical, easy to learn, to make programs,
or models, to build a clear final user interface, and where you find a lot of
examples in the bibliography (books),...
The second (Vensim) and the others are more complex, but not more difficult to
use, because take advantage of the windows capabilities. Referring to Vensim,
and as you speak about the predator-prey models, I invite you to visit the
paper "A simulation model for partially substituting telecommunication services"
in the address: http://ourworld.compuserve.com/homepage ... es/sd96htm
or also into: http://web.mit.edu/jsterman/www/SD96/home.html
where we explore the possibilities of Vensim to build this kind of models, with
the tools like Sensitivity analysis, parameters calibration, reality check,...
I hope your comments.

A cordial handshake of Antonio Barron

-------------------------------- &&&&&&&&&& --------------------------

Estimado amigo:
Esta sirve para saludarte, decirte si tengo algun compromiso pendiente
contigo, y solicitarte que me informes lo antes posible de tus avances con
la dinamica de sistemas.
Quiero reunir las diversas experiencias de todos aquellos que pueda
contactar entre gentes conocidas sobre el uso de la dinamica de sistemas, herra
mientas empleadas, publicaciones, trabajos, seminarios, ... e informar de todo
ello a traves del correo, web, y otras vias.
Te agradezco encarecidamente tu atencion.
Ah, no quiero desaprovechar esta ocasion para anunciarte la proxima ce
lebracion de un curso sobre "Sistemas Dinamicos", su metodologia, y el uso de
Vensim. Al respecto, puedes sugerirme lo que se te ocurra.
Un sincero apreton de manos, en la confianza de vernos pronto.
Antonio
