| Abstract: | This paper applies the algorithm of knowledge acquisition of incomplete information system based on tolerance relation and discernibility matrix to analyze the decision-making problem.According to contrastive analyses of results between incomplete decision-making table and complete decision-making table,validity of knowledge acquisition of incomplete information system is verified.The results show that the method of information acquisition in incomplete information system can efficiently control knowledge missing and extremely information expanding. |
