Neighborhood covering rough set model of fuzzy decision system


Bai-Ting Zhao and Xiao-Fen Jia

The neighborhood covering rough set model is established for the fuzziness of decision system. Firstly, the knowledge representation of fuzzy decision system is analyzed. Then fuzzy neighborhood relation is proposed to measure the fuzziness of the decision system. Finally prove that the classical indiscernibility relations and classical neighborhood relationship are special case of fuzzy neighborhood relations. Fuzzy neighborhood covering rough set model solved the problem of processing fuzzy attribute, and deal with the hybrid decision system which including both of fuzzy attributes and numerical attributes. The proved model expanded the applications of rough set.
