摘要
A relation system on two universal sets is a natural extension of a relation system on a universal set. This paper studies attribute reduction algorithms for relation systems on two universal sets. Based on two new discernibility matrices, we propose two reduction algorithms for relation systems and relation decision systems on two universal sets. As a corollary, we derive respectively the attribute reduction algorithms for relation systems and relation decision systems on one universal set.
