System dynamics is an approach to understanding the nonlinear behaviour of complex systems over time using stocks and flows, internal feedback loops and time delays.omputer software is used to simulate a system dynamics model of the situation being studied. Running what if simulations to test certain policies on such a model can greatly aid in understanding how the system changes over time.
