| 摘 要： | 针对评价多指标优劣中属性权值难以确定的问题，笔者提出了基于粗糙集的TOPSIS综合评价的应用算法，利用粗糙集进行权重确定，把粗糙集与TOPSIS相结合，提出了基于粗糙集的TOPSIS综合评价方法，以属性重要度作为各个属性的权值，对信息系统进行加权分析，得出了总体排序结果，并通过算例验证了该方法的有效性.

| Abstract: | The presence of more information doesn’t usually generate a corresponding increase.The rough set theory was introduced into evaluating the significance of the system parameters.The presence of irrelevant information will decrease the effectiveness of the algorithm.The authors proposed a solution to improve the quality,that is an attribute-weighted algorithm based on rough set theory.Firstly,The authors computed values for the weight of every attribute.Then combination of rough set and TOPSIS for comprehensive evaluation is described.The proposed method was applied in example and the result showed that it is effective. |
