The World3 model is a system dynamics model for computer simulation of interactions between population, industrial growth, food production and limits in the ecosystems of the Earth. It was originally produced and used by a Club of Rome study that produced the model and the book ''The Limits to Growth''. The principal creators of the model were Donella Meadows, Dennis Meadows, and Jørgen Randers. The model was documented in the book ''Dynamics of Growth in a Finite World''. It added new features to Jay W. Forrester's World2 model. Since World3 was originally created it has had minor tweaks to get to the World3/91 model used in the book ''Beyond the Limits'', later improved to get the World3/2000 model distributed by the Institute for Policy and Social Science Research and finally the World3/2004 model used in the book Limits to growth: the 30 year update ((synopsis) ). World3 is one of several global models that have been generated throughout the world (Mesarovic/Pestel Model, Bariloche Model, MOIRA Model, SARU Model, FUGI Model) and is probably the model that generated the spark for all later models. == Model == The model consisted of several interacting parts. Each of these dealt with a different system of the model. The main systems were *the food system, dealing with agriculture and food production, *the industrial system, *the population system, *the non-renewable resources system, *the pollution system. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「world3」の詳細全文を読む スポンサード リンク
