![]() ![]() The susceptible stock is overall affected by three feedback loops: vaccination, immunization, and reinfection, representing the inflows and outflows of the susceptible stock. The stocks are always calculated as people, and the flows are in people per day. ![]() The first step is to construct the initial structure – define major stocks and flows, seen as the model’s backbone or skeleton. The model serves as a general foundation for further epidemiological simulations and system dynamics modeling. This tutorial describes how the system dynamics simulation model was constructed for the Covid-19 pandemic using AnyLogic Software. As system dynamic modeling allows for a deeper understanding of the manifestation and dynamics of disease, it was helpful when examining the implications of the pandemic on the supply chain of semiconductor companies. ![]() System dynamics modeling, which incorporates systems thinking to understand and map complex events as well as correlations, can aid in predicting future outcomes of the pandemic and generate key learnings.

You can pack your code into a jar and import it in AnyLogic like any other external Java package. It is easy and can be very powerful to use external Java libraries in AnyLogic.Īnother thing to consider: If you have projects with lots of algorithms and data structures, why not develop them outside of AnyLogic, in a standard Java development environment like Eclipse? This way debugging and unit testing can be much more intensive then it is possible in AnyLogic and you can reuse this components easily in other Java or AnyLogic projects. That's the beauty of integrating external Java packages. ![]() I just created an empty graph using a normal AnyLogic variable, without any additional code. I can set an AnyLogic variable to the type Graph and give it the initial value new SparseMultigraph(). In the package there is a class called graph. Since you loaded the whole package name prefix, you can now access all classes of the package as if they were directly part of AnyLogic. Example: With the import you can write anywhere in your project Graph and it will work, without the import you would have to always write .Graph. This step is not obligatory, but if you don't do it, in your code you will always have to reference the full package path of every library item you want to access.
