...Li Li; Xican Li Purpose In order to solve the decision-making problem that the attributive weight and attributive value are both interval grey numbers, this paper tries to construct a multi-attribute grey decision-making model based on generalized greyness of interval grey number. Design...

...Li Zhang; Xican Li Purpose Aim to the limitations of grey relational analysis of interval grey number, based on the generalized greyness of interval grey number, this paper tries to construct a grey angle cosine relational degree model from the perspective of proximity and similarity. Design...

...Li Li; Xican Li Purpose In order to make full use of the generalized greyness of interval grey number, this paper analyzes the properties and its applications of generalized greyness. Design/methodology/approach Firstly, the static properties of generalized greyness in bounded background...

.... Then, the generalized greyness of interval grey number is used to modify the estimation factors of modeling samples and test samples to improve the correlation. Finally, the hyper-spectral prediction model of soil organic matter is established by using the fuzzy recognition theory, and the model is optimized...

.../methodology/approach First, this paper gives the definitions of the lower bound domain, the value domain, the upper bound domain of interval grey number and the generalized measure and the generalized greyness of interval grey number. Then, based on the grey relational theory, this paper proposes the model...
