By analyzing the problems of the foundational describe quantity of grey systems and the requirement for system identification to the mathematical model,the structural grey number in the information cognition theory into strctural grey vector and structural grey matrix is extended. Thereby,the grey system is defined,the grey pattern andthe universal representation of grey system are obtained.
There are some of defects in the classical the first-price sealed auction model,whose conditions are restricted too much to fit the real situation,after that it is verified with thoughts of grey system.
GM (1,1) model plays an important role in theory and application research of grey system, but is only applicable to the array data denoted by whitenization number,and is helpless to the array data denoted by interval grey number.
Meanwhile this thesis introduces the Grey System Theory (Grey System Theory hereafter refers to as GST) into the evaluation of enterprise competitive ability based on absorbing the research results of the predecessor. The theory that the thesis applies mainly is Grey Relational Analysis (Grey Relational Analysis hereafter refers to as GRA).
同时在吸收前人研究成果的基础上,将灰色系统理论(Grey System Theory以下简称GST)引入到企业竞争力评价之中,本文应用的主要是灰色关联分析(Grey Relational Analysis以下简称GRA)。
