部分信息已知、部分信息未知的系统称为灰色系统。灰色系统理论是研究解决灰色系统建模、预测、决策和控制的理论,是八十年代初期由我国学者邓聚龙提出的,它把控制论的观点和方法延伸到社会、经济、生态等抽象系统,把自动控制科学和运筹学的数学方法结合起来,发展了一套解决信息不完备系统的理论方法,对未来学的研究也有重要意义。在短短几 Part of the information is known, part of the system is unknown information known as the gray system. The theory of gray system is to study and solve the theory of gray system modeling, prediction, decision-making and control. It was put forward by our country scholar Deng Julong in the early 1980s. It extends the viewpoints and methods of cybernetics to abstract systems such as society, economy and ecology, By combining the mathematical methods of automatic control science and operations research, a set of theoretical methods to solve the incomplete information system has been developed, which is also of great significance for the study of futurology.
