Abstract: Classical decision-theoretic rough set was proposed based on only one cost matrix,which dose not take the diversity and complexity of cost into account.To make up for the shortcomings, a risk analysis method based on multi-cost fusion was introduced and a decision-theoretic rough set method based on weighted multi-cost was proposed. Futher-more,the properties and the relations of these kinds of rough sets were discussed.The measure and cost relations of them were analyzed.Finally,the validity and robustness of the method were verified by UCI dataset.
