Writing an SD Conference Paper
It’s review time for SD conference papers again. As usual, there’s a lot of variance in quality: really good stuff, stuff that isn’t SD, and good ideas imprisoned in a bad presentation. A few thoughts on how to write a good conference paper, in no particular order: Read a bunch of good SD papers, by … Continue reading “Writing an SD Conference Paper”
In search of SD conference excellence
I was pleasantly surprised by the quality of presentations I attended at the SD conference in St. Gallen. Many of the posters were also very good – the society seems to have been successful in overcoming the booby-prize stigma, making it a pleasure to graze on the often-excellent work in a compact format (if only … Continue reading “In search of SD conference excellence”
Writing a good system dynamics paper II
It’s SD conference paper review time again. Last year I took notes while reviewing, in an attempt to capture the attributes of a good paper. A few additional thoughts: No model is perfect, but it pays to ask yourself, will your model stand up to critique? Model-data comparison is extremely valuable and too seldom done, … Continue reading “Writing a good system dynamics paper II”

Meta MetaSD
I was looking at my google stats the other day, curious what posts interest people most. The answer was surprising. Guess what’s #1? It’s not “Are Causal Loop Diagrams Useful?” (That’s #2.) It’s not what I’d consider my best technical work, like Bathtub Statistics or Fun with 1D Vector Fields. It’s not about something controversial, … Continue reading “Meta MetaSD”
A Geoff Coyle reading list
The System Dynamics Society reports that SD pioneer Geoff Coyle has passed away. We report the sad news that longtime system dynamicist R. Geoffrey Coyle died on November 19, 2012. Geoff was 74. He started his career as a mining engineer. Having completed a PhD in Operations Research, he came to Cambridge, Massachusetts from the … Continue reading “A Geoff Coyle reading list”
Doing quality simulation research
Unless the Journal of Irreproducible Results is your target, you should check out this paper: Rahmandad, H., Sterman J., (forthcoming). Reporting Guidelines for Simulation-based Research in Social Sciences Abstract: Reproducibility of research is critical for the healthy growth and accumulation of reliable knowledge, and simulation-based research is no exception. However, studies show many simulation-based studies … Continue reading “Doing quality simulation research”
The Economic Long Wave
This is John Sterman’s model of long waves (long-duration economic cycles), driven by capital accumulation dynamics. This version is replicated from a JEBO article, STERMAN, J. D. (1985) A Behavioral Model of the Economic Long Wave. Journal of Economic Behavior and Organization, 6, 17-53. There’s some interesting related literature (including other economic models in this … Continue reading “The Economic Long Wave”
The secret to successful system dynamics modeling
Whenever a student wandered in late to a lecture at MIT, Jim Hines would announce, “… and that’s the secret to system dynamics.” If you were one of those perpetually late students, who’s struggled without the secret ever since, I will now reveal it. ”The key to successful modeling is to keep one’s understanding of … Continue reading “The secret to successful system dynamics modeling”
