A System Dynamics Bibliography list

True to the web, the Desert Island Dynamics link on my pages is no longer valid. The correct link is: http://web.mit.edu/jsterman/www/DID.html While looking for a new copy of DID, I ran across a few other useful resources: The PowerSim Institute has a searchable bibliography: http://www.psiminst.com...

mobility

Peter Allen at Cranfield in the UK has done some very interesting spatially disaggregated urban models (of Brussels, I think), that may be relevant to your interests. Mobility wasnt the focus, but was an important component. I dont have contact information at my fingertips, but there are links to so...

Waste Treatment and Urban Recycling Models

Friends, I just received the following query, seeking models of waste treatment and urban recycling. While I was able to make a few general suggestions (see end of message), I dont know of any readily available models that exactly suit Mr. Yamauchis needs. I know theres been a lot of work in these a...

Incorporating variable structure in SD

Several people have asked me for citations to Hartmut Bossels work on orientors and Bert de Vries et. al. on layering a GA onto an SD model. Thanks go to Joel Rahn for finding this one: >Hartmuts work came to mind as I read previous posts. Your item >inspired me to find one of the original reference...

Exploring new strategies with SD games

Kjeld & Syeds question led me to ask what the difference is between models for the exploratory stage of strategy development and management training. The key, I think, is that in strategy development you may not have a good model of the system, probably because you dont understand the loops in a...

Incorporating variable structure in SD

Kostis raised a great question and I cant wait to see all the other replies. I think theres already been a great deal of work aimed at creating models with variable structure. It generally falls into the complexity theory realm - genetic algorithms and genetic programming, classifiers, cellular auto...

Documentation standards

A while back, Stever Wehrenberg asked me whether I knew of any utilities that could link a set of documentation (in a word processor or database) with a model. I didnt have an answer for him, but the question got me thinking about what really ought to be built into our software (or the heads of prac...

Greenhouse Gas Reduction policy models.

(The following is a slight rewrite of my direct response to Paige Browns query. I will try to place some of the models and papers mentioned below on a web page soon). Dear Paige, John Sterman forwarded your query about greenhouse gas policy models to me. My dissertation research involves the creatio...
