System Dynamics Pitfalls and Pointers
Governing Business Rules in System Dynamics Models
Systemic structure underpins the way complex problems behave. This is
particularly so for feedback mechanisms. When building models we have
to pay particular attention to the rules that govern the
flows and control the operation of feedback mechanisms.
This is not
just a matter of identifying all the rules that might
operate and including them. Not all rules are of equal
importance. So, it does not make sense to include every
possible rule. To do so would result in models that
would be as complicated as the real world. Complicated models
are hard to fully understand and almost impossible to build
without making errors.
When constructing models, we need to include the
most important structural elements. These need to be connected according
to the most influential governing business rules.
The following is designed
to explain how to identify the most influential governing business
rules which might apply and how to include them in
our system dynamics models
