Consider the following "Sustaining the Forest" model intended to provide another example of how unexpected the behavior of a web of extended interactions can be.
Analysis has served us well in developing the understanding of things, at least to a point. Though analysis will not allow us to answer the why questions about things. For that we need synthesis. One might consider analysis and synthesis two sides of a coin that one shouldn't attempt to separate.
Part 1 demonstrates Picture primitives and Links to create representations of interactions. These are made visually attractive because the Picture primitives are overlay'd with images.
The following model was submitted by Lise Inman & Keith Margerison for inclusion in the ILE currently under development. I think it's a useful model which gets interesting as the arrival interval gets smaller and the queue backs up. So, what do you think of the model and what insights can we surface with this model?
The simple savings account is used to demonstrate the nature of a reinforcing loop. Change the initial amount and interest rate and run the model to see the implications of changing these values.
Yesterday's actions are responsible for the world we experience today. And today's actions are responsible for the world that we will experience tomorrow. The "Creating the Future" model is intended to provide a better sense of the common process associated with the unexpected unfolding of the future..
Use a bathtub model to investigate the manner in which inflows and outflows govern the quantity of a stock. Extend the structure to create and investigate the relationships of a goal seeking balancing loop.
Investigations into the relationships responsible for the success and failure of nations. This investigation was prompted after reading numerous references on the subject and perceiving that *Why Nations Fail: The Origins of Power, Prosperity, and Poverty* by Acemoglu and Robinson seem to make a great deal of sense.
Thoughts on why storytelling is critical for enabling others to understand relationship models once they're developed. This was done for Deeanna Burleson Topics in Systems Science Apr 2019.
Faced with a performance gap the two most obvious responses are to work harder or work smarter. There are trade offs associated with each, some obvious, some not so obvious.
Based on a dialogue on the System Dynamics mailing list regarding the current level of acceptance of System Dynamics after it has been promoted for over 70 years I dredged up the following set of influences as a thought exercise. This is an example of a Drifting Goals Archetype.
