Furthermore,fuzzy covering on universe is proposed,three different operations on the coverings are formed and then some significant results are gained.

The approximations and reduction in fuzzy covering-based rough sets are also studied.

Novel sensor placement method based on complete information coverage in sensor networks;

Aiming at the coverage problem in sensor networks, this paper proposes an analysis approach of resource-constrained information coverage.

Enterprise diagnostic model and its solving strategies based on fuzzy set-covering;

Classification of expansive soil based on fuzzy information optimization disposal;

Evaluation method of the multi-attribute scheme based on entropy weight of fuzzy information;

Fuzzy Information Processing Used in Warship s Stages Assessment;

The synthesis evaluation theory of vague informationIn the application of the check-up system on cadres;

Meanwhile it discusses the composition of text information,and analyzes three types of information-the subjective information,the objective information and the vague information,and more,it gives some analysis to the distribution.
