By making use of the advantage of characterizing granularity of partial granulation, different from the single equivalence relation in the classical rough set theory, this algorithm can study one decision table from different angles and different hierarch

该算法利用了偏序粒在粒度表达上的优势,区别于经典粗糙集理论中采用的单一等价关系,对同一决策表从不同的角度和多个层次来研究。
