Applicability and multidimensional synthetic applicability of fuzzy sets;

To solve the problem of track initiation for distributed heterogeneous sensor network under asynchronous sampling condition,the fuzzy synthetic approximation between the set of measurements and a target is defined based on the theory of fuzzy sets.

We proposed the lateral,the depth and the whole proximity,and set up the quantitative models based on partitioning central line by boundaries and constrained Delaunay triangular network.

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.
