A Tragedy of the Commons situation exists whenever two or more activities, each, which in order to produce results, rely on a shared limited resource. Results for these activities continue to develop as long as their use of the limited resource doesn't exceed the resource limit. Once this limit is reached the results produced by each activity are limited to the level at which the resource is replenished. See also Archetypes.

All the following have a common characteristic.

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.

We often set out to solve a problem or accomplish some particular result and things seem to go as planned. As time progresses it seems that progress becomes more and more difficult, if not impossible, and things may actually become worse than when we started. When this happens it is typically a Fixes that Fail structure that's operating. See also Archetypes.

An implementation of the classic Game of Life using agent based modeling.

Rules:

• A live cell with less than two alive neighbors dies.
• A live cell with more than three alive neighbors dies.
• A dead cell with three neighbors becomes alive.

This is the sample model used as a demo for enfolding and unfolding a model. This is what we had to do before the Storytelling feature was developed. Save this one for posterity!

A simple Susceptible - Infected - Recovered disease as a stock and flow model.

Simple savings account.

The limits to growth structure is based on the basic growth structure. And, as should be obvious, nothing grows forever as growth requires resources. Those required resources become a limits to growth. 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.

While these pictures represent very different things there is a common essence.

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.
