This section contains a
selection of models developed by various students, teachers, researchers
and consultants to depict the dynamics of specific problem situations.
The models have been developed to demonstrate specific dynamic
hypotheses. Such models are highly valuable to aid learning and to
demonstrate what these important contributors have done in the system
In many cases the original
models were developed in modelling languages no longer widely used, or
using unfamiliar software applications. In those cases the aim has been
to convert models directly to Powersim™ Studio. Unfortunately,
adaptation or modification of original models might have been necessary
because of incomplete code listings, or to depict graphically what it is
believed the original author set out to explain.
None of the models contained in
this section are claimed to be the work of any person other than the
original author. In each case the work of the original author is
Selected models have been
developed ab initio, based on problems described by authors or
System Dynamics Models from Literature
are described in the summaries that follow.
