Fuchs: Modeling of Uniform Dynamical Systems  —  Chapter 2
CHAPTER 2: From Model Structure to System Behavior


Dynamics is the result of the storage, flow, and production of certain easily visualized quantities. That was the message of Chapter 1 and we saw how models of processes could be built upon this image.
Here we will take a closer look at a series of models from the simplest possible to some more complex ones. This will allow us to realize how different types of dynamics—from simple growth or decay to complex oscillations—emerge as a consequence of different model structures. Here is the second message of system dynamics modeling: the behavior of a system is the consequence of its (model) structure. The models discussed here are available in the CBT unit. They are listed at the end of Chapter 2 of the CBT unit in Section 2.8.
