The notion of a rough set was originally proposed by Pawlak (1982). Later on, Dubois and Prade (1990) introduced fuzzy rough sets as a fuzzy generalization of rough sets. In this paper, we present a more general approach to the fuzzification of rough sets. Specifically, we define a broad...
This paper presents a comparative study of variable precision fuzzy rough sets based on residuated lattices, in which we compare variable precision L-fuzzy rough sets with the preexisting models. A variable precision upper L-fuzzy rough approximation operator is proposed with L-fuzzy granules based ...

Thus, the distribution center location problem can be solved more efficiently. Analysis using numerical examples has proven the optimization reliability of the algorithm, and the result obtained is promising. 展开 关键词: location rough sets distribution center interactive multi-objective fuzzy decision ...
Combining rough sets and fuzzy sets together, a fuzzy modeling method is put forward. Using information reasoning and data mining technology, a rough fuzzy model of four-phase intersections is built from the measured data and the model has been successfully used in the simulation research of traff...
