Study on the Multi-attribute Decision Model of Grey Target Based on Interval Number

Dang Yaoguo,Liu Sifeng,Liu Bin

Strategic Study of CAE 2005, Volume 7, Issue 8,   Pages 31-35

Abstract: define an interval number to denote this index value, but none has studied the interval number decision modelin grey target decision.Based on the above, the multi-attribute decision model of grey target based on interval number is derived, which extends the grey target decision model from real number sequence to interval number sequenceand richens the grey theories in grey target decision.

The Optimization of Grey Model GM (1,1)

Luo Dang,Liu Sifeng,Dang Yaoguo

Strategic Study of CAE 2003, Volume 5, Issue 8,   Pages 50-53

Abstract:

This paper analyzes the reason that grey model GM (1,1) often makes errors in simulated data.GM (1,1) about the simulation, it can be concluded that the structure method of background value in greymodel GM (1,1) has an important influence on the prediction and adaptability of the model.The optimum background value makes grey model GM (1,1) have better fitting and forecasting precision.

An Axiomatic Definition of Degree of Greyness of Grey Number

Liu Sifeng,Li Yi

Strategic Study of CAE 2004, Volume 6, Issue 8,   Pages 91-94

Abstract:

In this paper, an axiomatic system for the definition of degree of greyness of grey number is builtbased on discussion with two definitions of degree of greyness of grey number which have been put forwardTaking axioms as the criterion for definition of degree of grayness of grey number, a new formula fordefinition of degree of grayness of grey number has been formed with measure of the right range of greynumber and the background or field which is brought about by the grey number.
