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

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.

This is the Fire the Bunch model which depicts a difficulty associated with decreasing the accounts receivable delay in a particular situation.

Mouse over the various elements for a descriptions of the relationships.

Macros are very useful for defining functions that need to be repeatedly at various places in the model.

What do activities of these images have in common?

This model contains components supporting the Fire the Bunch example.

This is my first attempt at creating a simple Agent Based Simulation Model. Nothing fancy, just something that works.

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.

This is an example of dialogue mapping using the new picture link feature.

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).

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

All the following have a common characteristic.

Part 1 demonstrates Picture primitives and Links to create representations of interactions. These are made visually attractive because the Picture primitives are overlayed with images.

This is the entry model that describes the four building blocks, Stock, Flow, Variable and LInk, used to develop models.

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.

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