Abstract: In order to get the reasonable and objective evaluation index weights, rough set theory based intelligent evaluation model is constructed. According to the problem of index-weight acquirement in accordance with the condition of small sample data, we try to divide the decision table into several blocks and use hierarchical way to get index weight values, based on rough set theory. At the end of this paper, experimental results prove the superiority of the rough set intelligent evaluation model.
