Bill: Interesting point. I think our loose use of terminology might have created some confusion. Drawing from the GST jargon, the systems we model are ABSTRACT systems built around specific problems or families of problems. We try not to model CONCRETE systems representing organisms with a discernab...

I have developed a simple model of the growth of the Malaysian resort Sarawak, which I use as a classroom exercise. Sarawak set out to develop Ecotourism as a policy goal, but things are apparentlygoing in a different direction there. Contact me if you need details. Khalid Saeed From: Khalid Saeed <...

Jim, I think the need to drink is the sliding goal, which indeed would be further intensified by the increasing acceptance you have described. I agree social outcast is an inaccurate term. We are perhaps dealing more with self perception than with the others perception. Self-perception of awkwardnes...

Jim, I think, there is also a sliding goal archetype present in the college drinking process. Drinking might relieve a perception of social awkwardness in the short run (negative feedback), but addiction resulting from it would create a social outcast in the long run exacerbating the need to escape,...

David, An excellent observation. Both too little slack and too much slack can contribute to risk. An example might be that qulaity is at risk when there is too much inventory, efficiency is at risk when there is munificence. In any case, risk management would require understanding the nature of the ...

Id suggest first constructing a reference mode describing the dynamics problem pattern you are addressing. You might wish also to see: Saeed, K. Trade Relations in a Global Economy.

As much as I find George Backuss approach to using Vensim software for risk management very sophisticated, I wish to caution that the sophistication of an analytical process has little to do with its efficacy for the problem it is addressing. Risk arises often from operations with very little slack ...

This is a digression from the accreditation debate, but I note that we are already talking about what skills are necessary for successful practice. It seems to me that the most productive people in system dynamics have been the ones who colonized an application area. Having said that I wish to haste...
