Aiming at practical character of ventilation system in uranium mine well,through deciding the evaluation index system,a grey comprehensive evaluation model for rationality of ventilation system in uranium mine well is established based on grey correlation theory.
With this method,we built a weighed grey correlation matrix of each survivability design scheme vs different evaluation index by grey correlation theory,and calculated grey correlation projection values of the design schemes comparatively to the perfect scheme according to vector projection theory. The grey relation projection values can be used for evaluation of the schemes.
By combining the grey incidence theory with the fuzzy sets theory, a grey pattern recognition method based on fuzzy grey incidence analysis for interval grey number sequences is proposed and the confidence level of the result of the grey pattern recognition is also evaluated.
Aimed at the problem of target type classification and in the light of the reality of our ground-based air defense army,this paper introduces the principles of target type classification based on Grey incidence theory,presents a model and the scheme of target type classification after analyzing the primary factors which affect airplane type reorganization.
This paper generalizes the grey incidence theory for individual multi objective decision making to group decision making. The concept of individual imagined optimum effect and group imagined optimum effect is presented, and a grey analytical method of multi objective group decision making problem is proposed.
Combining grey-relational theory and Euclidean distance, a new method for computing degree of similarity in case-based reasoning (CBR) was presented. And the systematic approach of intelligent fault diagnosis based on CBR was put forward, which included representation, search and updates of the cases.
In this paper, we apply CBR (case-based reasoning) method to the partner search and optimizing system, and establish a model of partner choice system. The way of establishing case and its evaluation value databases is discussed. A method of calculating the similarity degree based on grey-relational theory and fuzzy-set theory is put forward.
In this paper, we apply GBR (case - based reasoning) method to the partner search and optimizing system, and establish a model of partner choice system. The way of establishing case and its e-valuation value databases is discussed. A method of calculating the similarity degree based on grey - relational theory and fuzzy - set theory is put forward.
In the 100 meter running teaching, the grey related theory is used in the researches of the relation between 100 meter running performance and physical qualities. It's probed that the practice of 30 meter sprint, 30 meter start, standing long jump, standing triple jump, 150 meter running are effective means to improve the 100 meter running performance.
