Abstract: This paper obtains the uncertain discernable term set based on discernable matrix of the information system and proposes the graphic method based on table factor graph.With this method，all minimal subset can be resolved and the computational complexity is less than solution from definition.Example shows the validity of this method.
摘要： 在文[1]由差别矩阵计算信息系统核的基础上得到未定差别项组，提出了基于表格因子图的图解法。利用该方法能准确地求出信息系统中所有的最小子集，且计算量少于由定义来约简。举例说明了该方法的有效性。
