Instability in Pull Systems (flexible kanbans)
Paulo Goncalves has been working on exactly the issue of instability in pull systems, with Intel as a case study. Paulo did his doctoral work here at the MIT System Dynamics Group and is now on the faculty of the University of Miami. He can be reached at Paulo Goncalves <paulog@miami.edu>. John Ster...

Global warming and structure versus behaviour
My friend Geoff Coyle is right that we need longer time horizons than those of politicians or business leaders if we are to deal appropriately with challenges such as global warming. However, with all due respect, it is wrong to suggest that anthropogenically induced global warming is questionable s...

Where are we in the Long waves
The discussion of the long wave (Kondratieff cycle) and where in it the US and world economy might be would benefit from reference to the extensive body of work done on this topic by the MIT system dynamics group, dating back to the early 1970s. None of this has apparently been cited by any of the w...

Traffic jams and congestion

The distance between you and the car in front plays the role of inventory. The distance between the cars accumulates the difference...

Can system dynamics models "learn"
Requiring a model be able to rewrite its own equations before we will deem it able to learn seems overly restrictive: >"Models that Learn [are] Models which add, delete, or edit its own >equations, and/or add or delete objects (stocks, flows, constants, >tables, etc.) based on the models own ou...

learning and deterministic models
Several writers in the thread on whether models can learn have made the assertion that system dynamics models are deterministic and that only modeling methods that involve stochastic elements (e.g. genetic algorithms) can learn. I dont want to debate the latter point, but I strongly object to the as...
