At AIT system dynamics curriculum is offered in a multidisciplinary program - Infrastructure Planning and Management, which is located in the School of Civil Engineering. The Infrastructure Planning and Management program was created to respond to the changing human resources needs of the Asia Pacif...

This is to respond to Arlen Wolperts comment on the implications of my comment on the quality of my own models. Firstly, it is not for me to judge the quality of my own work; my academic peers would do this. Given that the models have been published in a number of learned journals and the two books ...

Given that system dynamics is directed at problem solving rather than modeling concrete systems per se, most models we build subsume abstract closed systems created around patterns representing specific or generic problems. As such, a general model of an open system might be hard to find in system d...

Interesting questions. I would say the quality of the model is established, as in other scientific endeavors though peer review. The issue of quality of modeling process is not that simple, but I have a rather considered response to this question documented in paper I discussed recently at MIT. I be...

I wish to add a word to a very fine summarizing done by George on the subject. I would perhaps be repeating what I have said earlier whenever the question of stepping up the effort to sell SD has been brought up. Good products sell themselves and organiztions creating sound production prosper. Jay F...

In my opinion, system in system dynamics means an abstract set of relationships existing only to represent a problem behavior aka reference mode. The term holistic view is an attitude that must prevail when delineating the reference mode or interpreting the behavior of the system of relationships bu...

Asian Institute of Technology in Bangkok offers Masters and PhD programs in a number of fields. System Dynamics Curriculum is taught in the Infrastructure Planning and Management Program and a methodological concentration is offered. Please send your mailing address if you would like to receive prog...

I am a bit preturbed about the discussion on the SDR format. While there are a number of publications serving the consulting and training interests, SDR is one of the very few journals dedicated to SD aimed at the academic community. There of course is a lot of room for improving its quality, but ch...

What are SD models? Just wished to add that these are not models of any system per se, but of problems/processes/patterns. If we see parameters as inputs, they fall under the definition of open systems. If we look at feedback context, they are closed. The fact is they are abstract systems that exist...

To: John Wolfden You seem to be considering modeling of implicit processes and intangible variables, which have a great influence on system behavior, but which are rarely included in formal analyses as it is difficult to represent them. Fortunately, system dynamics is very amenable to doing this. Yo...
