Theories for Developing Causal Loop Diagrams

Post by ularoch@ibm.net »

hi,
validating a system dynamics diagram without simulation has in our
experience never payed out unless in reinforcing (erroneous) preconceptions.
For this we think are responsible two reasons:
1. the role of levels comes out only in simulation
2. real world models are almost without exception highly nonlinear, so we
think only sober siulation work will reveal the models characteristics
including whatever one wants to validate

"validating a model" in current practice based only on a diagram is one of
the receipts sold by software such as micrographics flow-charter for static
structure analysis..
