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.

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

An Addiction structure is the same as the Shifting the Burden structure though with the annoying aspect that one becomes addicted to the side effect ensuring that Fundamental Solution won't get implemented and the Symptomatic Solution will be applied repeatedly, and likely with greater frequency. See also Archetypes.

When the relevant interactions are identified it's appropriate to identify which elements are the responsibility of which stakeholders, which elements are part of the addressable interactions and which elements are part of the environment.

How easy it is to crate a relationship map, or model as it is more often referred to because the term is much shorter.

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.

A basic savings account model.

We never seem to have enough time. Is Time Management an answer or just a myth?

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.

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.

Model is created by Gene Bellinger. Original model can be accessed from https://insightmaker.com/insight/2249/Adjusting-the-Shower-SFD.

Based on Toward a General Theory of Societal Collapse which references Tainter's Model.

Leverage Point Modeling (LPM) is a demonstrated approach for improved planning and spending for Operations and Support (O&S) activities. LPM is a continuous-event simulation technique that uses the System Dynamics approach of model building. Dr. Nathaniel Mass championed the potential of LPM, and adapted it for the Department of Defense (DoD) as a tool for jumping to a higher performance curve as a means of offsetting higher costs and declining budgets. The purpose of LPM is to test policies and investments that improve mission capability for a given level of investment or funding. It is particularly used to evaluate investments in component reliability and parts availability. Ref: http://bit.ly/aT44kB

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).

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.
