Abstract

The Grey System Theory, first proposed by Professor Julong Deng in 1982, avoids the inherent defects of conventional, statistical methods and only requires a limited amount of data to estimate the behaviour of an uncertain system. During the quarter century, with the hard work by scholars', the grey theory has been successfully applied to research in industry, social systems, ecological systems, economy, geography, traffic, management, education, environment, physical etc. In summary, the main purpose of the grey system theory focuses on the relation between the analysis model construction, and for the following circumstances such as: no certainty, multi-data input, discrete data, and insufficient data, through predicting and decision-making.

Objectives

• Soft Computing

• Fuzzy System

• Optimization

Tutorial Materials

According to the study of the grey system theory, the field of the grey system can be summarized into seven parts:

• Grey generating: Relational generating and prediction generating

• Grey relational analysis: GRA

• Grey prediction: GM (1,1)

• Grey weighting: Grey entropy, GM(1,N) and GM(0,N)

• Grey statistics and grey clustering

• Grey decision-making and Grey programming

• Grey control

Meantime, the future research of grey system theory can be divided into a few parts

• Creation: To enhance the theory of the grey system, such as the isomorphism theory in grey generating, the if and only if condition for class ratio, the cardinal of grey relational grade, and the whole theory of grey shadow equation, etc.

• Contrast: Use the grey system theory method to analyze the same case and compare the result with the results derived from the traditional method (such as fuzzy method, time series method, etc.)

• Improvement: Under the original mathematics models, add the grey system theory method to make the results more convincing and practical. Also, create the toolbox is the future of this field.

• Application: The trend is toward business field, management field and education field. And can get a clear research direction.

• Combination: The combination of soft computing theory, such as Fuzzy-Grey, Grey-GA, Rough sets-Grey, etc. will be the trend.
