Our simple dynamic-simulation model shows that the global supply of Rare Earth Elements is limited for meeting the future demands of new technologies. Unless improved recycling policies are adapted strategic elements may become scarce in the next half-century as a result of a “peak Rare Earths Elements” phenomenon. The model results also show that the market alone cannot solve the resource ...

Study of System Dynamics System Dynamics Society

The concept of endogenous change is fundamental to the System Dynamics approach. It dictates aspects of model formulation: exogenous disturbances are seen at most as triggers of system behavior (like displacing a pendulum); the causes are contained within the structure of the system itself (like the interaction of a pendulum’s position and momentum that produces oscillations).

System Dynamics - Tool/Concept/Definition

System Dynamics. System dynamics is a simulation modeling language for understanding the behavior of complex dynamic systems. Invented by Jay Forrester of MIT in the mid-1950s, the basic language models the feedback loop structure of a system by using nodes (stocks, constants, and variables), relationships between nodes (arrows), table functions (a type of constant), and time delays.
