灰色关联度是灰色系统理论中的一个主要内容。灰色系统是指既含有已知信息,又含有未知的或非确知信息的系统。如果是已知信息的系统,称作白色系统。黑色系统则是指未知的或非确知的信息系统。鉴于真实系统绝大部分是灰色的,我国科学家邓聚龙教授于1982年创立了灰色系统理论,在解决工业、农业、军事、科研等许多实际问题上获得成功,受到国内外科学界的广泛重视。 灰色系统理论包括的内容较多,有关联度的分析,数据生成、评估、建模、预测、决策和控制等。本文仅讨论灰色关联度在棉花育种上应用的可能性,作为灰色系统理论及其方法应用于棉花育种工作的初步尝试。
Gray relational theory is a major part of gray system theory. A gray system is a system that contains both known and unknown information. If it is a system of known information, it is called a white system. Black system refers to the unknown or not sure information system. In view of the fact that the real system is mostly gray, Professor Deng Ju-long, a Chinese scientist, founded the gray system theory in 1982 and succeeded in solving many practical problems in industry, agriculture, military affairs and scientific research and was widely valued by the scientific community at home and abroad. Gray system theory includes more content, analysis of related degrees, data generation, assessment, modeling, prediction, decision-making and control. This article only discusses the possibility of using gray relational degree in cotton breeding as a preliminary attempt of applying gray system theory and its method to cotton breeding.
