DYNAMO (programming language)

DYNAMO, short for DYNAmic MOdels, is a simulation language and accompanying graphical notation created for the system dynamics method of modeling complex systems over time. It was developed in the late 1950s under the direction of Jay Wright Forrester at the M.I.T. Computation Center, with major contributions from Phyllis Fox, Alexander L. Pugh III and Grace Duren. Though DYNAMO began as a tool for industrial dynamics, its use quickly spread to population studies, resource depletion modeling and urban planning. Its most notable application was the system dynamics simulation behind the Club of Rome's 1972 report Limits to Growth, which used DYNAMO to model global resource and population trends. The language has since fallen out of active use.
