Dynamics Simulation Model of the Economic System in Mining Area

摘要

The system dynamics is a new subject that was put forward by Professor J. W. Forrester in American MIT in 1950s. It is extensively applied to systematic problems of high phase, nonlinear, multidimensionality, multiple feedback and complicated time-variation. In this paper, the complex system in mining area is divided into five parts – resources, environment, economy, population, and science and technology. The five parts are regarded as five sub-models. By taking the economic subsystem as an example, the SD model of complex system in mining area is established. This model has certain universality and practicability.
