Inventory Model v3.0 adds target inventory adjustment to maintain desired service level. See also: Inventory Model v2.0.

Escape behavior often results in more stress than one escapes from.

An example using custom units to convert a flow from one units to another.

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

Initial causal loop diagram for the influences leading to the acceptance of Systems Thinking.

When we address situations we tend to do so with myopic limited awareness of the real nature of the situation and our actions tend to produce unintended consequences which make the situation worse or create other problems that have to be dealt with by us or others.

All the following have a common characteristic.

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

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

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.

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).

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

Inventory Model v4.0 calculates min days inv & max days inv and makes adjustments for desired service level. See also: Inventory Model v3.0.

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.

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

All the following have a common characteristic.

There are numerous influences which work against the possibility of sustainable capitalism though there are a few that might be put in place to actually support its emergence.

This is a conceptual presentation for what Chapter 5 might become as archetypes evolution.

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

Our actions are based on our beliefs and the results of those actions are the basis for our beliefs. The difficulty we create for ourselves is that we make assumptions as to how to interpret the results we select based on our beliefs. As a result we are often operating on a flawed perspective of reality.

This model contains components supporting the Fire the Bunch example.
