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)。
The calculation result shows that a higher accuracy could be obtained by applying the grey system theory to prediction of the test data of fatigue life of metal materials,and a valuable method was proposed for shortening the test time of fatigue life of metal materials.
Based on the grey system,grey clustering model of comprehensive evaluation for computer requirement risk is put forward,and draw a meaningful conclusion,and it provides scientific basis for the quantitative evaluation result.
This paper applies the grey system theories for the forecasting of the future price of buildings to the improvement of the traditional hypothetical development method and raise the precision of valuation.
The paper presents a model, GM(1,1) -S,for the national fresh fruit yeild based on the Grey system theory and the 1970-1987 data cf national total output of fresh fruit. And the national prediction between 1988 and 2000 is predicted as well.
Based on the date of the products of industrial solid waste material , this paper establishs a GM(1,1) forecast model using the grey system(1,1) theory, and forecasts the future of tendency for the products of industrial solid waste meterial in Ning guo City and provides scientific basis for the environmental manegement.
The GM (1,1) model in the grey system theory was proposed to predict the test data of fatigue life of metal materials,the aim was to largely cut short test time,save test cost,quickly obtain reliable index.
