Contrary to some earlier statements, there is ample evidence that SD can be used to model exactly the issues referred to below. All of this comes, however, with one important caveat that I think is the source of confusion: Paraphasing an early statement by Professor Forrester, SD can be used to mode...

>>How many system dynamicists does it take to screw in a lightbulb? I think this question is best understood by considering how some of the great members of the field might tackle the question: The Pugh-Roberts folk might develop a sophisticated model to predict when the bulbs would burn out. Ventan...

I dont think anybody claims that the beer game captures the dynamics normally associated with brewery supply chains. I believe it has it origin in Professor Forresters initial studies of General Electrics difficulties with instability in its refrigerator manufacturing plants. In fact the game was or...

I have a PhD student, John Foster, working on this problem. He is trying to develop a fully behavioral model of how somebody might solve such an optimization problem. It turns out to be quite a hard problem and we could not find a formulation in the existing literature that really captured it. Many ...

SD List members,

a number of you have pointed out to me that the paper actually will not
download at the moment. I am in the process of trying to fix this.

Sorry for the problems,

Nelson

SD List members: After my talk, The Transition Problem in Product Development, at the SD conference this summer, a number of people expressed interest in the associated paper and model. At long last these are now available if you point your browswer to the following address http://web.mit.edu/nelson...

Some more thoughts on Accreditation: First, let met try to point out the bias I am bringing to this issue. I have a degree in System Dynamics and my current livelihood depends on other people also wanting to get such degrees, so it should fairly obvious where my preferences lie. Given that here are ...

Some Thoughts On Professional Accreditation, Jay Forrester has often framed system dynamics as a profession similar to engineering or medicine which requires a combination of academic training, experience, and apprenticeship. Following this model, accreditation might be appropriate since there are s...
