Abstract: As a hot research topic, granular computing makes the multi-level research questions possible. If granular computing is introduced to decision formal context, there are more accurate decision rules. In this paper, we define the multiple granularity decision formal context from the perspective of granularity of a g-tree, then the consistent properties between before and after granulation are studied. The relationship between rules of before and after granulation are given.

Key words: granular computing, decision formal context, consistent, rule acquisition
