A Hierarchical Fuzzy Decision-making Method
Qinghua Zhang · Microelectronics & Computer · 2009
In this paper,for a decision information system with fuzzy condition attribute,a new method processing fuzzy decision information system is proposed.Firstly,the fuzzy similarity relation is constituted between the object in a domain with the Hai-Ming similar degree measure,and a hierarchical structure of partition space is given with the method of fuzzy clustering.And then with the Pawlak's rough set model,the hierarchical rules(knowledge)is acquired based on the hierarchical structure of partition space.Finally,the attribute reduction in fuzzy information system is discussed,and the reduced rule is acquired.
