This paper firstly points out the deficiency of intrusion detection method based on distance measure;then presents a new fuzzy anomaly detection method based on lattice degree of nearness for reducing false positive rate and false negative rate.

Research the algorithm of mahalanobis and advanced lattice degree of nearness which used in radar emitter recognition.

Method of designing hierarchical structure of SVM decision tree based on lattice close-degree;

In order to measure the similarity between the granules,we define lattice close-degree of granular computing which is based on the conventional Fuzzy set close-degree,and offer the related properties.

In this thesis the new method and lattice closeness degree will be synthesized together to analyse the relation among the properties in the database.

Fuzzy approach degree-based research on occurrence of karstic collapse

Based on the conceptions of approach degree and weight distance, an improved model is developed for assessing the atmospheric environment quality in Urumqi, Xinjiang, in this paper.

In this paper, the distribution type can be judged conveniently from a group of test data with approach degree theory in Fuzzy mathematics.

Synthetical condition assessment of long span suspension bridge based on closeness degree and FAHP;

Conceptual design of relays based on the theory of fuzzy closeness degree;

And,the concept of closeness degree of fuzzy mathematics was used to compute the distance between the life cycle cost/effectiveness and the ideal point/negative ideal point.
