A Growth and Underinvestment structure is simply an elaborated Limits to Growth structure where the growth inhibitor is part of another Balancing Loop with an external standard and some delay. The real nasty thing about this structure is that the two Balancing Loops form a single Reinforcing Loop which inhibits growth.

The goal seeking structure endeavors to bring a balance between a current state and a desired state. This is one of the two foundation archetypes. The other being the growth structure. See also Archetypes.

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.

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

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.

All the following have a common characteristic.

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

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

Hypertension Generic Patient Flow CLD.

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.

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

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).

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.

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

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

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

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

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

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.
