This simulation is constructed as part of the Masters thesis of Corne du Plooy where a general stepwise transition is applied to the archetypes, turning them into simualtions. In this simulation the structure of the Escalation Archetype is explored in the context of how social media is able to pepetuate hate between two groups of people.

This is the third system archetype being simulated in the Masters thesis work of Corné du Plooy through the University of Witwatersrand, South Africa. The research is focused on formulated a 11 step system dynamics method of translating the system archetypes into simulations. The method is tested out on four different archetypes with a combination of Delphi rounds in order to improve the method and final simulations. This archetype is specifically on the eroding goals on SA education, where the matriculation rate has been drastically improved yet it is questionable if this can be translated to actual skill improvements

A simple game to explore the some of the financial realities of planning better for retirement. You start at the age of 65 and the simulation runs for 40 more years. Your goal is to prevent your life quality to deplete to 0 by adjusting the desireable min and max ranges of your pension value. Additionally you can adjust the intensity of your reactions.

Small Model to explore the hypothesis that problems are the drivers to building new skills. This means that when there is no problems, people do not build skills and start losing them. The loss of skills reduces the problem solving rate and problems accumulate. Higher problems then force society to learn skills again and solve problems which restarts the cycle.

This simulation gives the user the ability to specify their own current condition (weight, age, height etc.), choose their exercise regime and eating plans. The simulator then gives a projection for the user's weight for the next year (at a weekly resolution). Please take note that most of the pictures are navigation buttons to different screens, so remember to click on the pictures. I have personally used this simulator to successfully lose more than 20 kg. Hope you find this as valuable as I did. Good luck with your weight journey!

Uploading a Bundle from Zip

Instead of creating bundles, categories, and assemblies one by one, you can upload a single zip file that contains all of your bundle's content. To create your zipped bundle, make a folder with your bundle's name and add subfolders with your categories' names. The folder tree should have the same structure that you want the categories to have in your bundle. Place your assembly .stmx files in the appropriate category folders, then zip your bundle folder and upload it using the Upload Bundle from Zip link above.

Assemblies, Bundles, and Categories

Assemblies are self contained models that demonstrate common ways to connect together building blocks and that can be used as parts of other models. This is analogous to using prefabricated wall and roof pieces to construct a house.

Bundles are groups of assemblies with a common use or theme. For example, a Health Care bundle might contain a variety of assemblies that aid in creating health care models. When you download assemblies from the isee Exchange™, you download an entire bundle, rather than individual assemblies.

Categories are subgroups of assemblies within a bundle. For example, a Health Care bundle might contain a Funding category for assemblies related to the management of hospital funds. All assemblies must be assigned to a category—they cannot be assigned to the root of a bundle.

Assemblies, bundles, and categories can be created and uploaded to the isee Exchange™ via the options on the Manage My Assemblies page. To learn more, visit our help pages, or take our assemblies tutorial.

Sim App (Sim)

An interface that allows users to interact with a model.

Image of a sim

Sim apps allow users to interact with a model using buttons, sliders, knobs, tables, graphs, and storytelling. These interactions help users understand how parts of a system interact.

Interfaces are created by model authors in the Stella desktop software and can be uploaded to the isee Exchange™.

Model

A diagram that represents how elements in a system influence one another.

Image of a model

Models are mathematical representations of how elements in a system are connected and interact (e.g., ecosystems, organizations, supply chains). When running models on the isee Exchange™, results can be viewed in output devices like graphs and tables.

Models appear in the isee Exchange™ directory when authors upload them from the Stella® desktop software or create them with Stella Online™.

Causal Loop Diagram (CLD)

A map that represents the feedback structure of a system.

Image of a CLD

CLDs are high-level maps that represents the feedback structure of a system and easily communicate the essence of a model. They appear in the isee Exchange™ when authors upload them from the Stella desktop software or create them with Stella Online™.
