Based on the characteristics and properties of green cutting tools, the main feature factors for evaluating green cutting tools and the fuzzy comprehensive evaluation method of green proximity are put forward.

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.
