Plastic pollution has become one of the most vital issues for the environment. The usage of plastic has been increased rapidly because it is inexpensive and durable, thus more plastics are being generated. As a result, the huge quantity of generated plastic ends up in the landfill as they are not biodegradable. Plastics and their byproducts are littering our cities, oceans, and waterways which causes harm to humans, animals as well as plants through toxic pollutants. A huge number of plastic wastes eventually ends up in the ocean, meaning that marine animals are also at risk. Plastic takes hundreds or even thousand years to break down, so the environmental damage is longlasting. Our main policy is to decrease the plastic pollution by increasing plastic recycle rate. Plastic recycling refers to the process of recovering waste plastic and reprocessing the materials into functional and useful products. This procedure is known as the plastic recycling process. At present around 50% plastics are thrown away only after single use. By implementing this policy, we can reuse the plastics and decrease the number of plastics that goes into the landfill. Reusing will also decrease the number of newly generated plastic. As a result of the policy, less plastics will go into the landfill, the amount of plastic sent to incineration will be reduced, more plastics will be recycled, and new plastic generation rate will be decreased. In this way plastic pollution will be decreased eventually and it will provide a positive impact on the environment.

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.

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.

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™.
