一、灰色系统理论1982年,我国学者邓聚龙教授创立了灰色系统理论,灰色系统是指既有黑色又有白色参数的系统。描述灰色系统的三要素是:(1)灰色参数:已知其部分性质,未知其准确数字的参数;(2)灰色方程:一个既有白色参数又有灰色参数的代数方程;(3)灰色矩阵:行列数已知,某些元素是灰的的矩阵,常常是大系统、复杂系统的代表。灰色系统理论主张从事物的内部结构和参数去研究,允许系统中存在灰色参数,并充分利用系统中部分存在的白色信
First, the gray system theory In 1982, Professor Deng Jurong Chinese scholars founded the gray system theory, the gray system refers to both the black and white parameters of the system. The three elements that describe a gray system are: (1) gray parameter: a parameter whose part property is known and its exact number is unknown; (2) gray equation: an algebraic equation with both white parameter and gray parameter; Matrix: The number of rows and columns is known, some of the elements are gray matrices, often represented by large systems and complex systems. Gray system theory advocates the study of the internal structure and parameters of things, and allows the existence of gray parameters in the system, and makes full use of white letters existing in the system
