Stock and flow diagrams are composed of two main elements: stocks and flows. Stocks are the accumulations or quantities of something in the system, such as water, money, population, or inventory.

Figure 1 shows the main symbols used in stock-flow diagrams based on the energy language (Odum and Odum, 2000), where shields indicate the stocks, line arrows the flows, and solid arrows the processes ...

System Dynamics is a methodology for modeling and simulating dynamically complex systems, which are characterized by feedback loops, nonlinearity, and time delays. It uses Causal Loop Diagrams and ...

Lots of epidemiologists use “stock-flow diagrams” to describe ordinary differential equation (ODE) models of disease dynamics.We’ve created two tools to help them. The first, called StockFlow.jl, is ...
