Attribute Reduction based on Heuristic Knowledge and Its Application on Evaluation System

XIAO Jian-hua 1,WU Jin-pei 2,YANG Shu-zi 1 (1. School of Mechanics,Huazhong University of Science & Technology,Wuhan 430074,China; 2. Institute of Intelligent Technology & Systems,Wuyi University,Jiangmen 529020,China)  
For the purpose of solving the NP problem emerging in the process of knowledge reduction, the concept of condition-decision relationship degree(CDD) that used in determining the importance of each condition attribute has been put forward in this paper. By using the value of each attribute's CDD as heuristic knowledge in deciding the sequence of attribute reduction, the condition attribute sets can be reduced fleetly and efficaciously finally. In the end of paper, the evaluation systems of Guangdong province natural science funds is used to illuminate the validity of the new algorithm.
