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.

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.

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.

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 delays associated with adjusting the shower is a very common example of the Balancing Loop with Delay Systems Archetype.

Implications of a variation between deadline and expected project completion date.

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!

While Knowledge-Centered Support is rather easy to understand and has amazing potential realizing that potential seems to be quite elusive.

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.

Examples of reinforcing and balancing loops enhanced with images to maybe them more visually engaging.

A spatially aware, agent based model of disease spread. There are three classes of people: susceptible (healthy), infected (sick and infectious), and recovered (healthy and temporarily immune).
