- Abstract:
-
In order to solve uncertainty measure problem in data analysis of rough set, this study first constructs a new type of conditional entropy of the objective concept and conditional entropy of decision knowledge, with consideration of the degree of missing of conditional attributes, and moreover, proposes the conditional entropy-based attribute weight determination technique and a complementary method for incomplete attributes with minimum conditional entropy, so as to solve a kind of incomplete multi-attribute decision-making problem whose attribute weight is completely unknown. The real practical application shows that the proposed method can effectively combine coarse-grained preliminary classification information to objectively determine the value of decision factors, having strong explanatory significance, and the obtained decision results are more reasonable and effective.
