【Abstract】 System dynamics was founded by Professor Jay W.Forrester in 1956 at MIT. The field is based on developed concepts in system theory, feedback theory, information theory and on the available techniques of computer simulation. It is a unique tool for dealing with questions about the way systems behave through time. The approach has been spplied to a far wider range of problems, such as the implications of exponential growth in a finite world in early 1970’s. More recently, system dynamics has been used to create a large-scale socioeconomic model of the U.S. The model is bringing to light the behavior of the economic long wave.更多还原
