The establishment of a goal is one way to provide a basis for results thought is has its difficulties.

Success to the successful archetype represents two reinforcing structures which may be in a delicate balance though as soon as one gains a small advantage the resource allocation favors the more successful and the result is then rapidly skewed in the direction of the more successful. See also Archetypes.

My first simulation model example.

The goal seeking structure endeavors to bring a balance between a current state and a desired state. This is one of the two foundation archetypes. The other being the growth structure. See also Archetypes.

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.

Rich Pictures are simply pictorial representations of the relations between a number of relevant elements. The strength of rich pictures is that they're free form without any formal rules, which also tends to be the shortcoming of rich pictures.

The purpose of this model is to have the user change the value of stocks, flows and converters to experience a variety of different graphical results. Understanding this generic model is important pre-requisite to learning about intravenous drugs in the body, radioactivity, self-esteem, water flowing from a drain and many other basic natural systems.

It's relatively well understood that you can't be all things to all people. Somewhere one has to make choices. An Attractiveness Principle Systems Archetype is essentially a Limits to Growth Systems Archetype with multiple limits, all of which can not be addressed equally. See also Archetypes.

This common archetype of systems that include relapse or recidivism allows exploration of the unintended effects of increasing upstream capacity and swamping downstream capacity. The increase in the relapse rate eventually returns to swamp upstream capacity as well.

Success to the successful archetype represents two reinforcing structures which may be in a delicate balance though as soon as one gains a small advantage the resource allocation favors the more successful and the result is then rapidly skewed in the direction of the more successful. See also Archetypes.

Simple bathtub model to show the difference between Stock and Flow. Run the model with various values for filling and draining to see the implications.

The city of Bergen has a goal of becoming fossil-free in 2030. How do we get there? Some weeks ago, local experts from different domains came together and developed a causal loop diagram (CLD). This will form the skeleton for the modelling hackathon.

It's now time for the stakeholders to take the investigation resulting from leverage and craft a strategy which will address the current situation in a manner that is beneficial to the whole system.
