This model is based on the paper by Crokidakis, Nuno. (2020). *Data analysis and modeling of the evolution of COVID-19 in Brazil*. For further details, see the full paper here.

In addition to modeling a COVID-19 transmission system in Brazil, it shows the conversion of the system of differential equations into a stock-and-flow diagram.

Jay Forrester's major contribution was to propose a new language—System Dynamics—to represent systems of differential equations, which constitutes its solid mathematical foundation, developed by Newton and Leibniz in the 17th century.
