There seem to be two fortunate principles in SD modeling which make it quite amenable to representing spatial changes: 1. Spatial changes occur over time 2. decision rules depend only on current information and not on time. Forresters Urban Dynamics model has an implicit spatial dimension since it t...

Let me add a few references to work on water management modeling. Tony Picardi and I published following paper long time ago based on the consulting work at Development Analysis Associates. Picardi, A. C., and Saeed, K. 1979. Dynamics of Water Policy in South-Western Saudi Arabia. Simulation. 33(4):...

I am preparing a book project proposal on sustainable development for a MIT Press series. It would be a revised and enlarged edition, with some modification in presentation format of my earlier book "Towards Sustainable Development, Essays on System Analysis of National Policy." The publis...

Brundtland definition seems quite precise to me. Check out following papers: Acharya, S. R., and Saeed, K. , An Attempt to Operationalize the Recommendations of the "Limits to Growth" Study to Sustain Future of Mankind. System Dynamics Review. (12)4. 1996 (forthcoming) Saeed, K. An Attempt...

I agree, bells and whistles may do little to enhance the usefulness of a computer-based game. The way such a game is moderated might, however, greatly increase its impact. I have tried running People Express - a one person game - in a group mode with very positive results. This was with a group of b...

I have talked about this elsewhere in detail, but one way to assure a model has in it possibilities for structural change is to incorporate into the reference mode multiple case histories with contradicting patterns. This way, latent structure for re-enacting those patterns, and many more, is create...

Georges reminder is very important and I slapped myself for not mentioning the essential qualification in my earlier response. I should add that both references I provided deal with the growth of bureaucracy and its related resource allocation and productivity problems. Khalid Saeed Professor and Pr...

NT Tuan Barry Richmonds PhD work on the Growth of govt. should be of interest to you for a macro-level view. This should be avaialble from MIT libraries For a micro level perspective, see: Saeed, K. 1996. The Dynamics of Collegial Systems in the Developing Countries. Higher Education Policy. 9(1). 1...

I have used two sets of orders for groups in the same class, a step (4 to 8) and random noise (with mean 4 and std dev 1). The behavior is similar in the two cases, and it generates a good discussion about internal trends vs external disturbance. Khalid Khalid Saeed Professor and Program Coordinator...
