Rough sets theory (RS) is a new tool for processing fuzzy and uncertain knowledge, and has already been applied to many areas successfully. In this paper, by analyzing the basic characteristic of rough set, for the deficiency that the existing rough set model can't effectively solve data reduction and knowledge discovery with possibility feature, we propose rough sets model based on possibility measure...
Fuzzy techniques are playing an increasing role in current intelligent computations and optimizations. How to reasonably describe and measure uncertain information has been becoming urgent in many practical domains such as artificial intelligence, computer techniques, control and optimizations in complex manufacturing systems. In view of poor indistinct structure features of current measuring ways...
In making decision, fuzzy information should be filtered to strengthen or weaken the influence of some factors according to some decision consciousness. An axiomatic system for fuzzy information filter operators is put forward after analyzing the essential feature of the existing filter methods. A general way to establish a fuzzy information filter operator is given, and the applications of filter...
