The Application of Rough Comprehensive Evaluation Method

Firstly, the authors generalize the indiscernible relation to similarity relation, give a definition of $\lambda$-discernibility matrix; secondly, according to the properties of $\lambda$-discernibility matrix, an algorithm of computing significance of each condition attribute is put forward; thirdly, we give the comprehensive weight of each attribute according to subjective and objective weight; at last, the reasonable and available of this algorithm is accounted for through an example.
