一、什么是灰色系统所谓系统是指一个包含若干相互关联又相互制约元素所组成的具有某种功能的整体。如一个社会组织、一个经济区、一个工厂等都可以看成是一个系统。任何一个系统总是包含若干子系统,同时又被若干子系统所包围。到目前为止,描述系统的理论和方法很多。1948年美国控制论专家 N·维纳和1953年英国科学家 A·艾什比曾经用闭盒和黑盒来称呼内部信息一无所知的系统,从此以后,人们就常用颜色深浅来形容系统信息的完备程度。把内部特性完全已知的信息系统,称为白色系
First, what is the gray system The so-called system is a system that contains a number of interrelated and mutually constraining elements composed of a certain function of the whole. Such as a social organization, an economic zone, a factory, etc. can be seen as a system. Any one system always contains several subsystems, while being surrounded by several subsystems. So far, there are many theories and methods to describe the system. In 1948, when the American cyberneticist N · Wiener and the British scientist A. Ashby in 1953 once used the closed box and the black box to refer to the system without any knowledge of the internal information, people often use the color depth to describe the system information The degree of completeness. Information systems with fully known internal characteristics are called white lines
