| Abstract: | Based on the definition of the decision reduction and the discernibility matrix in the fuzzy object information system,The property of the discernibility matrix and relation between the discernibility matrix and decision reduction set are discussed.At the same time,A new significance of attribute is defined and taking it as heuristic information,a minimal decision reduction algorithm in the fuzzy object decision information system is designed.The result of the example shows that this algorithm is not only brief,but also effective. |
